-'se

Etymology
Originally a postposition attaching to a nominalized form of the verb, as seen by its 🇨🇬 cognates. In Ye'kwana, however, this suffix apparently never co-occurs with a nominalizer—likely the anomalous glottal stop at the start of the suffix is in fact itself a reduced form of the nominalizer in origin.

Usage notes
A verb marked with this suffix is negated by and pluralized with, both also found on adverbs and postpositions. If both markers are present they can appear in any order. However, a plural can also be formed with the noun plural clitic, in which case it combines with this suffix into the form.
