Complementizers in Michif are normally not independent words, but prefixes to specially inflected forms indicating that the clause is subordinate.
These verbs start with a prefix that can be called a complementizer, ee- (with variants), chi- or kaa-.
The complement can probably be introduced by a zero complementizer in a construction like 'he knows, I am good', or when an evidential is used.
