Preverbs (IPV) are particles which must be attached to verbs in order to function within a sentence.
The boldfaced elements in examples (1) and (2) illustrate preverbs in use. They are written with hyphens (-) to indicate that they are bound (much like dependent stem nouns) and cannot stand alone as words.
(1) miyo- “good; well”: miyo-nikamow “s/he sings well” ; miyo-masinahikēw “s/he writes well”, etc.
(2) āhkami- “persistently”: āhkami-nēhiyawētān “let’s keep speaking Cree”
