Derivational Verbal Morphology

Sereer seems to have at least some verbal derivational morphology. So far, we've seen:

Takes verb, makes verb:

• -ir, a reciprocal suffix
• -in, a causative suffix (e.g. gɛf "to break, explode (intr.)" --> gɛfin "break it"). Allomorphs -an or -n occur when co-occurring with person marking, and sometimes when another suffix precedes (e.g. χum 'to tie', χum-ir 'to tie RECP', χum-r-an 'to tie to each other' (061)
• -ooχ, which seems to be stativizing or anti-causative. Its derived forms are somewhat less semantically consistent than the others.
• -lɔɔχ/-nɔɔχ, a suffix of possibly causative meaning that has mutiple allomorphs

Takes verb, makes adjective:

• -u / -o, a suffix that takes a stative verb and turns it into an adjective (e.g. saɗik "to be strong, tough" -> saɗku "strong, tough"; maj "to be many" -> maju "many")

Takes verb, makes noun:

• -ir, a suffix that makes instrument-type nouns from verb stems (e.g. βɛʄ "to swim" --> bɛʄir "thing used to swim")
