have tenses are those of (1) time, and (2) interrogation: and of these, t is the sign of the past tense, and hò of the future; thus, atỳ, am here; tatỳ, was here; hò atỳ, will be here;—aìza, where is? taìza, where was? hò aìza, where will be?
Adverbial verbs are made from adverbs by putting the active prefix mank- before them; as, mànkatỳ, to come here; mankàny, to go there. Of these verbs, only mankàny has an imperative mood (mànkanèsa) or a relative voice (ànkanèsana), These are made to serve with all the other adverbs of place; as, mànkanèsa atỳ hìanào, 'come here'; nahòana nò tsỳ nànkanèsanào tàny? 'why did you not go there'?
With àvy (coming) put before them, they imply 'motion from', and are equivalent to hence, thence; as, àvy èo ìzy, 'he is coming thence, he is coming hither'.
Adverbs of place are made indefinite in meaning by being repeated with hò inserted; as, àtohòàto (or, àto hò àto), hereabouts; tèohòèo, thereabouts. They are also often used to express relations of time (as, tèo, recently, lately), especially when used indefinitely (as, tàtohòàto, or tàto hò àto, lately).
