Adjectives can be verbified and then appear in the shape of attributive verbs: haúki, pl. hauháki _hollow_; haúkäs _I am hollow_, haúkis _it is hollow_, hauhákis _they are hollow_. No real substantive verb being extant, its want is supplied by ómäs, mómäs, tóyäs _I am so, I am such_; these are conjugated regularly, and when connected with the verbals in -t (-at, -it, -ut) of any verb, compose a periphrastic conjugation which displays itself in an almost infinite number of forms.
