Verbs can be marked with several suffixes to add or change meaning. Some of these can be optional and their sequence varied, but in general they should be ordered:
STEM-(SIZE)-(MOOD)-(ASPECT)-(TENSE)-(NEGATIVE)
Example:
na empahipankoyek – 1SG run-DIM-able-PROG-PST-NEG – I was not able to keep jogging.
