Sudan Arabic Oral Stops The difference between the sets of phrases is pre-glottal non-obstruent and voiced stops. The explanation for this is that each oral consonant in one set has a nasal equivalent in the other set, and that the matched consonants are in harmonized distribution before vowels. Since the matched consonants are in harmonized distribution in other perspectives as well, they can be acquired from a single sequence of phonemes undetermined for obstruence and nasality, disallows the assignment of nasality to obstruents, and the nasal alternatives are caused by an exceptionless rule spreading nasality from a nasal vowel to any consonant that does not bear (+obstruent). Similar to the other languages of this kind, Ikwerre supports this rule independently.
This explains an otherwise confusing fact regarding the distribution of nasal consonants in languages of this kind: prevocalic nasal consonants normally fail to appear before vowels that do not occur with distinctive nasalization. For instance, if the oral vowels /a/ and /i/ have no distinctive nasal counterparts, nasal consonants normally do not appear before [a] and [i], whether or not it is nasalized. Lexical exceptions may come up from frozen compounds, loanwords, reduplications and the like. Such gaps supply an independent diagnostic of the absence of unique nasality in consonants.
