Allomorph

An allomorph is a variant form of a morpheme that is produced under certain conditions.

For example, the English article a has an allomorph an that appears before words starting with a vowel.

In Toaq, the tonal determiner has a non-tonal allomorph ló that can only appear when another grammatical process needs a full syllable to hold onto, such as in the context of object incorporation.

History

It used to be the case that the word jeı had an optional verb-tone allomorph used with pronouns, so that suq could be used as a "verb" that was really equivalent to jeı súq. However, nowadays people just say jeı súq.
