Michif end-of-word codas end in maximally two consonants.
For words of French origin, there is a cluster -sk in two words (zeusk 'as far as', pleusk 'more'), and the other clusters seem to have an /r/ as their first or second member:
port 'door'
risarv 'reserve'
zarb, narb 'tree'.
In words of Cree origin, almost only simple consonants are used as codas - this includes the pre-aspirated consonants /ht, hk/. The only exceptions to this are the clusters /sht/ and /shk/, as in keechishk 'barely', puuyuushk 'quitter' and /st/, which is a dialectal equivalent of /ht/.
