Derivational Verbal Morphology

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

• -uʔ / -oʔ, a suffix that takes a stative verb and turns it into an adjective (e.g. saɗik "to be strong, tough" -> saɗkuʔ "strong, tough"; maj "to be many" -> majuʔ "many")
• -ir, a suffix that makes instrument-type nouns from verb stems (e.g. βɛʄ "to swim" --> bɛʄir "thing used to swim")
• -ir, a suffix that might be reciprocal (?) (e.g. χas "to scold, berate" --> χasir "to argue")
• -in, a suffix that could be called applicative, transitivizing, or something like that (e.g. gɛf "to break, explode (intr.)" --> gɛfin "break it", translation unclear)
• -ooχ, of unclear meaning (examples needed)
