The third and final Modal prefix we shall look at is the Factual. The Factual has the form
wa- before h- or a vowel; otherwise it takes the form o'-. Just as with
the Optative and Future, after the Factual the Pronominal prefixes beginning
with h- lose the h-. Prefixes beginning with a vowel add a -'- to the
beginning; but the 1sP prefix ak- combines with the Factual to form ök-.
Look at the model.
