Nyimang is an altered form of “Nyima,” one of the mountains in the Ama homeland, which is now used as the name of the branch of Eastern Sudanic consisting of Ama [nyi] and Afitti [aft]. I will assume that Nyima is one of a group of four extant northern branches of the Eastern Sudanic family, the others being Nubian, the Nara language, and Taman.<sup id=fnref:2><a href=#fn:2 class=footnote-ref role=doc-noteref>2</a></sup></p><p>Ama examples unless otherwise stated are from the authors fieldwork verified with leading Ama writers who oversee literacy in the language.

For tone, Amas nearest relative Afitti has been described as having two contrastive tone levels,<sup id=fnref:3><a href=#fn:3 class=footnote-ref role=doc-noteref>3</a></sup> but Ama has three levels, which play a role in the verb system as well as the wider lexicon as shown in <strong>table 1</strong>.</p><table><thead><tr><th></th><th></th><th></th><th></th><th></th><th></th></tr></thead><tbody><tr><td>kɛ́r</td><td>woman</td><td>nɪ́</td><td>kill (factative)</td><td>ɕɪ́ɛ̄</td><td>do (transitive)</td></tr><tr><td>kɛ̄r</td><td>crane (bird sp.)</td><td>nɪ̄</td><td>kill (progressive 3rd person)</td><td>ɕɪ̄ɛ̄</td><td>say</td></tr><tr><td>kɛ̀r</td><td>around</td><td>nɪ̀</td><td>kill (progressive 1st/2nd person)</td><td>ɕɪ̀ɛ̄</td><td>do (intransitive)</td></tr></tbody></table><p><strong>Table 1: Level tone contrasts in Ama</strong></p><p>A brief overview of Ama morphosyntax can be gained by locating it in the typology of Heine and Vossen,<sup id=fnref:4><a href=#fn:4 class=footnote-ref role=doc-noteref>4</a></sup> which assesses African languages on the presence of nominal classification, nominal case, and verbal derivation.

It has SOV word order, although as we shall see, Ama is not strictly verb-final. It also has coverbs that occur with an inflecting light verb. As in Tama,<sup id=fnref:8><a href=#fn:8 class=footnote-ref role=doc-noteref>8</a></sup> most Ama verbs take their own inflections but coverbs are also seen quite frequently. Many Ama coverbs fit Stevensons characterization that the coverb occurs before the light verb stem <em>ɕɪɛ</em> “do/say” and is either an ideophone (with marked phonology such as reduplication or non-mid tone) or a word marked by the suffix <em>-ɛ̄n</em> (typically a borrowed verb).<sup id=fnref:9><a href=#fn:9 class=footnote-ref role=doc-noteref>9</a></sup> The form of the Ama coverb suffix <em>-ɛ̄n</em> matches the Fur co-verb suffix <em>-ɛn</em> ~ <em>-ɛŋ</em>.<sup id=fnref:10><a href=#fn:10 class=footnote-ref role=doc-noteref>10</a></sup> The transitivity of the predicate is distinguished in Ama by the tone on the light verb <em>ɕɪ̀ɛ̄/ɕɪ́ɛ̄</em>.</p><table><thead><tr><th>Intransitive coverbs</th><th></th><th>Transitive coverbs</th><th></th></tr></thead><tbody><tr><td>nʊ̄nʊ̄ɲ ɕɪ̀ɛ̄</td><td>hop</td><td>díɟí ɕɪ́ɛ̄</td><td>work</td></tr><tr><td>ɟɪ̀ɟɪ̀ɡ ɕɪ̀ɛ̄</td><td>speak angrily</td><td>ɟɛ̀rɟɛ̀r ɕɪ́ɛ̄</td><td>scatter</td></tr><tr><td>àɽɪ̀mɛ̀ ɕɪ̀ɛ̄</td><td>be angry</td><td>t̪úūl ɕɪ́ɛ̄</td><td>destroy</td></tr><tr><td>ōlɡ-ēn ɕɪ̀ɛ̄</td><td>cry</td><td>dɪ́ɡl-ɛ̄n ɕɪ́ɛ̄</td><td>gather (Kordofan Nubian *ɖigil)<sup id=fnref:11><a href=#fn:11 class=footnote-ref role=doc-noteref>11</a></sup></td></tr><tr><td>tɔ̄ɡl-ɛ̄n ɕɪ̀ɛ̄</td><td>tie oneself</td><td>fɔ̄ɟ-ɛ̄n ɕɪ́ɛ̄</td><td>make suffer</td></tr><tr><td>sɛ̀ɡ-ɛ̄n ɕɪ̀ɛ̄</td><td>complain</td><td>tɪ̄m-ɛ̄n ɕɪ́ɛ̄</td><td>finish</td></tr><tr><td></td><td></td><td>kɔ̄w-ɛ̄n ɕɪ́ɛ̄</td><td>iron (Sudanese Arabic <em>kowa</em>)</td></tr><tr><td></td><td></td><td>rɛ̄kb-ɛ̄n ɕɪ́ɛ̄</td><td>ride (Sudanese Arabic <em>rikib</em>)</td></tr><tr><td></td><td></td><td>mɪ̄skɪ̄l-ɛ̄n ɕɪ́ɛ̄</td><td>give someone a missed call (S.

Ama coverbs</strong></p><p>While Amas verb-final word order and use of coverbs are reminiscent of other Nilo-Saharan languages, relative clauses in Ama are of a globally rare type. Ama uses adjoined relative clauses at the end of the main clause, and these modify the last noun of the main clause.<sup id=fnref:12><a href=#fn:12 class=footnote-ref role=doc-noteref>12</a></sup><sup id=fnref:13><a href=#fn:13 class=footnote-ref role=doc-noteref>13</a></sup></p><p>(1)</p><p>(2)</p><p>The adjoined relative clause strategy means that verbs tend not to occur in noun phrases in Ama, although for completeness we should observe that they are not entirely excluded. Since it is impossible to modify the subject of a transitive clause by an adjoined relative clause, as it is separated by another object or oblique noun, speakers consulted confirmed that it is grammatically acceptable to modify a subject noun by a progressive verb within the noun phrase as in (3), although they felt this is not used much, and I have not found examples in texts. However, verb participles marked by the suffix <em>-ɔ̀</em> (or <em>-ò</em> by vowel harmony) also occur in noun phrases, including in texts as in (4) and (5).</p><p>(3)</p><p>(4)</p><p>(5)</p><p>Nevertheless, the adjoined relative clause strategy is an innovative feature of Ama that tends to place information about participants outside the noun phrase where they are mentioned. A similar distribution applies to the expression of number. Within the noun phrase, there are no number affixes, although there is a plural specifier <em>ŋɪ̄</em> or <em>ɡɪ̄</em> that can be used with rational nouns as seen in (6). Speakers consulted assess this specifier the same way as unmarked relative clauses within the noun phrase: acceptable, but not used much. However, Ama also has a post-verbal quantifier <em>ɡɪ̀</em> that can be used when there is a plural participant in the clause, as shown in (7).<sup id=fnref:14><a href=#fn:14 class=footnote-ref role=doc-noteref>14</a></sup></p><p>(6)</p><p>(7)</p><p>We will return to this tendency to express relative clauses and number late in the clause after considering other evidence from verb stems.</p><h2 id=ama-verb-stems class=hx>Ama Verb Stems<a class=hpar href=#ama-verb-stems></a></h2><p>Stevenson discovered the existence of two stems of each Ama verb.<sup id=fnref:15><a href=#fn:15 class=footnote-ref role=doc-noteref>15</a></sup> The forms of the two stems are not fully predictable from each other in general, and their usage depends on aspect.</p><h3 id=the-factativeprogressive-distinction class=hx>The FactativeProgressive Distinction<a class=hpar href=#the-factativeprogressive-distinction></a></h3><p>The aspectual functions of the two stems were described by Stevenson as definite and indefinite aspect, and relabeled as perfective and imperfective by more recent authors. However, the usage of the former stem meets the definition of “factative,”<sup id=fnref:16><a href=#fn:16 class=footnote-ref role=doc-noteref>16</a></sup> such that it has a past perfective reading when used for an active verb like “eat,” but a present continuous reading when used for a stative verb like “know.” The other stem has a present progressive reading, which is marginal for stative verbs where the meaning contribution of progressive to an already continuous verb is highly marked.<sup id=fnref:17><a href=#fn:17 class=footnote-ref role=doc-noteref>17</a></sup> The factativeprogressive analysis is helpful when we consider the history of these stems below.</p><table><thead><tr><th></th><th>active verb</th><th>stative verb</th></tr></thead><tbody><tr><td><strong>factative aspect</strong></td><td>t̪àl “ate” (past perfective)</td><td>t̪ʊ̄-máɪ́ “know” (present continuous)</td></tr><tr><td><strong>progressive aspect</strong></td><td>tām “is eating”</td><td>?máɪ́ “is knowing”</td></tr></tbody></table><p><strong>Table 4.

However, neither the factative stem nor the progressive stem is predictable from the other in general because: (i) factative stems belong to various theme vowel classes, and some belong to a class taking a formative prefix <em>t̪V-</em>; (ii) in some verbs the two stems have two different suppletive roots; and (iii) the progressive stems of some verbs require certain obligatory incorporated affixes.

More verbs with T/K marking</strong></p><p>T and K are well-known markers of singular and plural in Nilo-Saharan languages,<sup id=fnref:21><a href=#fn:21 class=footnote-ref role=doc-noteref>21</a></sup> but in Ama and Afitti where there is no T/K morphology on the noun, essentially the same alternation (<em>*t</em> becomes dental in the Nyima branch)<sup id=fnref:22><a href=#fn:22 class=footnote-ref role=doc-noteref>22</a></sup> is found on the verb. It also cuts into the characteristic CVC verb root shape, implying that it is an innovation on the verb. I therefore propose that this class of verbs attests the Nyima cognate of the wider Nilo-Saharan T/K alternation. This entails a chain of events in which the T/K alternation first moved from the noun (singular/plural) to the verb (singulactional/pluractional), and then shifted in meaning from verbal number to verbal aspect (factative/progressive).</p><p>Both steps in this proposed chain are indeed plausible cross-linguistically. As to the first step, the possibility of nominal plural markers being extended to verbal pluractionals is familiar from Chadic languages, where the same formal strategies such as first-syllable reduplication or <em>a</em>-infixation may be found in plural nouns and pluractional verbs.<sup id=fnref:23><a href=#fn:23 class=footnote-ref role=doc-noteref>23</a></sup> In the Nyima languages, the productive innovation at this step appears to have been the extension of singulative T to a verbal singulactional marker. This is seen in the fact that <em>t̪-</em> alternates with other consonants as well as <em>k</em> in Ama (<em>t̪ān-ɛ̄/wɛ̄n</em> “talk,” <em>t̪ɛ̀l-ɛ̄/wɛ̄ɛ́n</em> “see,” <em>t̪àl/tām</em> “eat”), or is prefixed in front of the root (<em>t̪ʊ́-wár-ɔ̄/wār</em> “want,” <em>t̪ī-ŋīl-ē/ŋɪ̄l</em> “laugh,” <em>t̪ì-fìl-è/fɪ̄l</em> “dance,” <em>t̪ū-mūs-ò/mús-èɡ</em> “run,” <em>t̪ʊ̄-máɪ́/máɪ́</em> “know,” <em>t̪-īlm-ò/ɪ́lɪ́m</em> “milk”). There is also external evidence from Nubian and Nara cited in <strong>table 6</strong> above that <em>*k</em> is the original initial consonant in <em>*kal</em> “eat” replaced by <em>t̪-</em> in Ama and Afitti.</p><p>As to the second step, the prospect of verbal number shifting to verbal aspect is supported by semantic affinity between pluractional and progressive. Progressive aspect often entails that a process that is iterated (&ldquo;is coughing,&rdquo; &ldquo;is milking&rdquo;) over the interval concerned.<sup id=fnref:24><a href=#fn:24 class=footnote-ref role=doc-noteref>24</a></sup> In Leggbo,<sup id=fnref:25><a href=#fn:25 class=footnote-ref role=doc-noteref>25</a></sup> a Niger-Congo language, the progressive form can have a pluractional reading in some verbs, and conversely, verbs that fail to form the regular progressive <em>C# → CC-i</em> because they already end in <em>CCi</em> can use the pluractional suffix <em>-azi</em> instead to express progressive aspect. In Spanish,<sup id=fnref:26><a href=#fn:26 class=footnote-ref role=doc-noteref>26</a></sup> a Romance language, there is a periphrastic paradigm between progressive (<em>estar</em> “be” + gerund), frequentative pluractional (<em>andar</em> “walk” + gerund), and incremental pluractional (<em>ir</em> “go” + gerund). The two Spanish pluractionals have been called “pseudo-progressives,” but conversely one could think of progressive aspect as pseudo-pluractional. What is somewhat surprising in Ama is that progressive stems, being morphologically more basic (see <strong>table 5</strong>), lack any devoted progressive affixes that would have formerly served as pluractional markers.<sup id=fnref:27><a href=#fn:27 class=footnote-ref role=doc-noteref>27</a></sup> However, some progressive marking is found in irregular alternations that reveal former pluractional stems.</p><p>In <em>t̪àl/tām</em> “eat,” the final <em>l/m</em> alternation is unique to this item in available word lists, although <em>l/n</em> occurs elsewhere (<em>kɪ́l/kín</em> “hear,” <em>t̪ɛ̀l-ɛ̄/wɛ̄ɛ́n</em> “see”). The final <em>l/m</em> alternation is nevertheless also found in Afitti (<em>t̪ə̀lɔ̀/tə̀m</em> “eat”) and in Kordofan Nubian (<em>*kol ~ kel/*kam</em> “eat”).<sup id=fnref:28><a href=#fn:28 class=footnote-ref role=doc-noteref>28</a></sup> Kordofan Nubian <em>*kam</em> is used with a plural object, a pluractional function, so in the Nyima branch the proposed shift pluractional → progressive derives the progressive function of final m found in Ama, just as it does for the initial <em>k</em> in <em>t̪/k</em> alternations or the <em>t</em> in <em>t̪àl/tām</em> “eat.” Furthermore, a final plosive in Old Nubian (ⲕⲁⲡ-<sup id=fnref:29><a href=#fn:29 class=footnote-ref role=doc-noteref>29</a></sup>; Nobiin <em>kab-</em>) suggests that the unique <em>m</em> in “eat” arose by assimilation of the final nasal (realized as <em>n</em> in the other Ama verbs mentioned) to a following <em>*b</em>, that was fully assimilated or incorporated in Old Nubian.</p><p>Seen in this light, the significance of moving T/K morphology onto verbs in the Nyima branch is that it renewed an existing system of irregular singulational/pluractional alternations. We then have a tangible account of where Amas missing noun morphology went, because formerly nominal morphology is found on the verb instead.</p><h3 id=concretization-of-core-clause-constituents class=hx>Concretization of Core Clause Constituents<a class=hpar href=#concretization-of-core-clause-constituents></a></h3><p>We can also now tie together this finding with the findings on verb syntax in
<a href=#syntax><span class=sup>www</span><i>§2</i></a>
. Both T/K number marking and relative clause modification have moved out of the noun phrase, and in these comparable changes we can observe a trend towards concretization of noun phrases, with number and clausal information about the participant being expressed later in the clause.</p><p>The trend towards concretization also affects the verb itself. T/K and other irregular stem alternations did not maintain their pluractional meaning, as this evolved into a more concrete construal of the predicate over an interval of time as progressive aspect. Since concretization affected the verb as well as noun phrases, it affected the entire core SOV clause, with plurality as well as relative clauses largely deferred to after the verb.</p><p>A role for concreteness in grammar was previously proposed in the Pirahã language of Brazil by Everett.<sup id=fnref:30><a href=#fn:30 class=footnote-ref role=doc-noteref>30</a></sup> Everetts approach remains highly controversial,<sup id=fnref:31><a href=#fn:31 class=footnote-ref role=doc-noteref>31</a></sup> particularly, I believe, in its attempt to constrain grammar by culture directly in the form of a synchronic “Immediacy of Experience Constraint” on admissible sentence constructions and lexemes in Pirahã. My proposal here is deliberately less ambitious, appealing to concreteness as a diachronic trend in the Nyima branch, not as a constraint on the current synchronic grammar of Ama. Thus, Ama typically attests a separation between a concrete SOV clause and post-verbal modification, but this is not a strict division in the grammar, because it is not impossible to express number or relative clauses within the noun phrase, just infrequent. The concretization process in Ama must also have been specific enough not to have eliminated adjectives from the noun phrase. Ama has adjectives, as shown in examples (8)(11), which occur as attributive modifiers of nouns in their unmarked form, whereas in predicates they are separated from the subject noun by a clause particle and occur as the complement of the inflecting copula verb <em>nɛ̄</em>.

Inward displacement of suffixes by an imperative or past suffix</strong></p><p>Both types of affix alternation in tables 11 and 12 involve low-tone suffixes in the final slot. Therefore, the development of all affix order alternations can be attributed to a single historical shift of all low-tone suffixes to the final slot. However, this shift is not realized in verbs containing two low-tone suffixes, because only one of them can go in the final slot. The only final-slot suffix that does not alternate is the imperative <em>-ɪ̀,</em> which leaves imperative as original to the final slot. Other suffixes originate from more internal slots to the left of the dual.</p><p>As for the origin of affix selection according to aspect, this presumably arose as an extension of the systematic stem selection that occurs for every verb in Nyima languages. This question remains complex, however, because each of the categories affected (past, passive, directional, ventive) will have its own history as to how alternating affixes were acquired in these conditions. One modest proposal is that the NES plural copula <em>*aɡ</em> shown earlier in <strong>table 6</strong> is the likely source of the progressive passive suffix <em>-àɡ</em> in Ama,<sup id=fnref:33><a href=#fn:33 class=footnote-ref role=doc-noteref>33</a></sup> via the shift from pluractional to progressive (
<a href=#tk><span class=sup>www</span><i>§3.3</i></a>
), and by a plausible assumption of a transition in passive marking strategy from use of a copula to morphological marking on the verb. This sourcing does not extend to the other passive suffix in factative aspect <em>-áɪ́,</em> however, which does not resemble the singular copula <em>*an</em>.

Only the dual suffix can occur without <em>-ar</em>, where in my data the dual suffix adds to the longer stem with <em>-ar</em> unless the short stem is suppletive (<em>t̪ī-ə̀/túŋ</em> “sleep,” t̪àl/<em>tām</em> “eat”) and can take the dual suffix without ambiguity with factative aspect.</p><table><thead><tr><th>singular</th><th>dual</th><th>distributive plural</th><th>gloss</th></tr></thead><tbody><tr><td>fá kɪ̄r-ār</td><td>à-fá kɪ̄r-ār-ɛ̄n</td><td>à-fá kɪ̄r-ɪ́d̪-ār</td><td>dont be cutting!</td></tr><tr><td>fá sāŋ-ār</td><td>à-fá sāŋ-ār-ɛ̄n</td><td>à-fá sāŋ-ɪ́d̪-ār</td><td>dont be searching!</td></tr><tr><td>fá túŋ-ār</td><td>à-fá túŋ-ɛ̄n</td><td>à-fá túŋ-ɪ́d̪-ār</td><td>dont be sleeping!</td></tr><tr><td>fá tām-ār</td><td>à-fá tām-ɛ̄n</td><td>à-fá tām-ɪ́d̪-ār</td><td>dont be eatingǃ</td></tr></tbody></table><p><strong>Table 14.

However, these connections are more in form than meaning, as the semantics is highly innovative in such notable shifts as plural → pluractional → progressive and reciprocal → dual, and in the drive towards concretization that has moved the expression of both relative clauses and number out of noun phrases to after the verb. In addition, the movement of low-tone suffixes to the final suffix slot, while itself a formal development, has further advanced the morphologization of aspect, so that stem selection, affix selection, and affix order all vary with aspect in Ama verbs. Next to these considerable changes, Amas stable distributive pluractional stands out as indicative of a wider Eastern Sudanic verbal category.</p><p>An explanation for the innovations found in Ama will not be found in influence from other languages of Sudan, because several of its innovations are extremely rare (adjoined relative clauses, dual verbal number, tone-driven affix order alternation). Instead of an influx of new forms, we have unusual internal evolution of existing forms, implying relative isolation. Ama then exemplifies what both Dahl and Trudgill call “mature phenomena,”<sup id=fnref:60><a href=#fn:60 class=footnote-ref role=doc-noteref>60</a></sup> found in languages of isolated small communities where the language has time to evolve based on an abundance of specific shared information in a closed society of intimates. Languages spoken by isolated societies of intimates are more likely to conventionalize complex morphological paradigms, unusual categories, and unusual syntax (maturation), whereas larger, multilingual social networks encourage simpler grammars in the sense of smaller paradigms, and pragmatically well-motivated categories and syntax that are found widely in language (pidginization). Aforementioned verbal features in Ama of dual number, irregular allomorphy (in suppletive roots and in the use of a second distributive suffix), fusion (in affixes like passive and ventive that mark aspect as well), polyfunctionality (of the progressive suffix <em>-ar</em> for mirativity or long stem formation), and multiple exponence (of aspect by stem selection, affix selection, and affix order), plus the unusual syntax of adjoined relative clauses, all look like mature language phenomena.<sup id=fnref:61><a href=#fn:61 class=footnote-ref role=doc-noteref>61</a></sup></p><p>Ama nominals, similarly, are known for their relatively rich case systems, but similar case paradigms are found in Nubian and other Northern East Sudanic languages, implying that the case system largely matured at an earlier stage and the resulting complexity is retained in all these languages. Thus, it is the verb system rather than the nominal system that provides evidence of maturation in the Nyima branch in particular.</p><p>The conclusion that Ama verbs (and post-verbal syntax) have matured as a result of Nyimas isolated position, away from the river systems that hosted speakers of other languages in the Sudan region in the past, faces the possible difficulty that contacts have in fact been proposed between Nyima and other Nuba Mountain groups. Thus, it is proposed that the Niger-Congo Nuba Mountain group Heiban borrowed accusative marking and basic vocabulary from Nyima.<sup id=fnref:62><a href=#fn:62 class=footnote-ref role=doc-noteref>62</a></sup> Such contact would have put a brake on maturation in Nyima, because the use of proto-Nyima for inter-group communication between first-language Nyima users and second-language Heiban users would not have supported further growth in complexity.<sup id=fnref:63><a href=#fn:63 class=footnote-ref role=doc-noteref>63</a></sup> However, it is not realistic that such contacts lasted for a large proportion of Nyima history, but rather were fairly temporary periods punctuating Nyimas longer isolation. Thus, the Heiban group has now developed separately in the eastern Nuba Mountains for something approaching two millennia (given the internal diversity of the ten Heiban languages found there) since its contact with Nyima.</p><p>Some time after the contact with Heiban, Rottland and Jakobi note the likelihood of contact of Kordofan Nubian with Ama and Afitti in the north-west Nuba Mountains before the arrival of Arabic as a <em>lingua franca</em> in the Nuba Mountains.<sup id=fnref:64><a href=#fn:64 class=footnote-ref role=doc-noteref>64</a></sup> Ama and Afitti are more lexically divergent than Kordofan Nubian and therefore were probably already separate communities when the Kordofan Nubians arrived. However, the innovation of dual marking on Ama verbs in the period after separation from Afitti still shows the hallmarks of maturation. It adds an extremely rare category, increases the occurrence of morphologically complex verbs by using a verbal marker in dual participant contexts that were not previously marked, and adds redundancy when agreeing with noun phrases containing two referents. This mature feature of Ama again suggests that any language contact with Kordofan Nubian occurred for only part of the time since Ama separated from Afitti.</p><p>This period nevertheless also reveals one significant example of simplification in Ama verbs that supports the idea that language contact occurred. Afitti has pronominal subject markers on the verb, seen earlier in <strong>table 13</strong>, which are absent in Ama. The pronominal prefixes are not the same in form as personal pronoun words in Afitti (1sg <em>oi</em> but 1sg prefix <em>kə-</em>),<sup id=fnref:65><a href=#fn:65 class=footnote-ref role=doc-noteref>65</a></sup> therefore they are not incorporated versions of the current pronoun words, but rather predate them. Some of the Afitti pronoun words (1sg <em>oi,</em> 2sg <em>i</em>)<sup id=fnref:66><a href=#fn:66 class=footnote-ref role=doc-noteref>66</a></sup> are similar to Ama (1sg <em>ɪ̀,</em> 2sg <em></em>) and must be retentions from proto-Nyima, hence the older pronominal prefixes must also be retentions in Afitti, but lost in Ama. Their loss in Ama is remarkable against the larger trend of growth in complexity of Ama verbs that we have examined in this paper. The predicted cause of this surprising reversal is pidginization under contact. That is, their loss is evidence that the Ama language was used for inter-group communication, presumably with the Kordofan Nubians, during which (and for which) Ama SOV sentences were simplified by dropping verbal subject marking. If Kordofan Nubians spoke Ama, then borrowing from Ama into Kordofan Nubian is also likely. In verbs, the obvious candidate for borrowing into Kordofan Nubian is the reciprocal suffix <em>-in</em>, as this is not attested elsewhere in Nubian.<sup id=fnref:67><a href=#fn:67 class=footnote-ref role=doc-noteref>67</a></sup> The following two-step scenario would then account for the facts: Ama was learned and used by Kordofan Nubians, during which Ama dropped verbal subject marking and its reciprocal suffix was borrowed into Kordofan Nubian; next, Ama returned to isolation in which the reciprocal suffix developed its dual function that is unique to Ama today.</p><section class=footnotes role=doc-endnotes><hr><ol><li id=fn:1 role=doc-endnote><p>Stevenson, <em>Grammar of the Nyimang Language</em> and “A survey of the phonetics and grammatical structure of the Nuba Mountain languages with particular reference to Otoro, Katcha and Nyimaŋ,” 40: p. 107. <a href=#fnref:1 class=footnote-backref role=doc-backlink>&#8617;&#xfe0e;</a></p></li><li id=fn:2 role=doc-endnote><p>Rilly, <em>Le méroïtique et sa famille linguistique,</em> §4. <a href=#fnref:2 class=footnote-backref role=doc-backlink>&#8617;&#xfe0e;</a></p></li><li id=fn:3 role=doc-endnote><p>de Voogt, “A Sketch of Afitti Phonology,” p. 47. <a href=#fnref:3 class=footnote-backref role=doc-backlink>&#8617;&#xfe0e;</a></p></li><li id=fn:4 role=doc-endnote><p>Heine & Vossen, “Sprachtypologie,” cited in Kröger, “Typology Put to Practical Use,” p. 159. <a href=#fnref:4 class=footnote-backref role=doc-backlink>&#8617;&#xfe0e;</a></p></li><li id=fn:5 role=doc-endnote><p>Norton, “Number in Ama verbs,” pp. 7576, 85; Stevenson, “A Survey of the Phonetics and Grammatical Structure of the Nuba Mountain Languages,” 41: pp. 175176. <a href=#fnref:5 class=footnote-backref role=doc-backlink>&#8617;&#xfe0e;</a></p></li><li id=fn:6 role=doc-endnote><p>Stevenson, <em>Grammar of the Nyimang Language,</em> §§210. <a href=#fnref:6 class=footnote-backref role=doc-backlink>&#8617;&#xfe0e;</a></p></li><li id=fn:7 role=doc-endnote><p>Dimmendaal, “Africas Verb-final Languages,” §9.2.3. <a href=#fnref:7 class=footnote-backref role=doc-backlink>&#8617;&#xfe0e;</a></p></li><li id=fn:8 role=doc-endnote><p>Dimmendaal, “Introduction” to <em>Coding Participant Marking,</em> pp. 67. <a href=#fnref:8 class=footnote-backref role=doc-backlink>&#8617;&#xfe0e;</a></p></li><li id=fn:9 role=doc-endnote><p>Stevenson, “A Survey of the Phonetics and Grammatical Structure of the Nuba Mountain Languages,” 41: p. 174. <a href=#fnref:9 class=footnote-backref role=doc-backlink>&#8617;&#xfe0e;</a></p></li><li id=fn:10 role=doc-endnote><p>Waag, <em>The Fur Verb and Its Context</em>, p. 49; low tone is unmarked in the Fur two-tone system. <a href=#fnref:10 class=footnote-backref role=doc-backlink>&#8617;&#xfe0e;</a></p></li><li id=fn:11 role=doc-endnote><p>Jakobi, <em>Kordofan Nubian,</em> p. 159.
