There is also another large group of verbs which again have only non-finite forms, in which the non-finite stem is unanalysable (as a verb, at least), thus there is no "e-/i-/j-" prefix. In most cases the participle of such verbs has the suffix "-tu" ("-du" if the stem ends in "n" or "l"). Occasionally we find zero or "-i" instead. This is replaced by "-tze" or "-te" in the verbal noun, and by nothing in the short stem. The stems of these "secondary" verbs may be (1) a nominal or other non-verbal stem (e.g. "poz-tu, garbi-tu..."), (2) a phrase (e.g. "ohera-tu"), (3) a Latin or Romance verbal stem (e.g. "barka-tu, kanta-tu...") or (4) an unanalysable (primary) verb stem (e.g. "har-tu").
