(5) sanati = “immediately after.” tsosanati woa = Go as soon as you have eaten. (6) si or sa = “after.” tsosi woa = Go when you have eaten. (7) leha or chakla denote concession. Ana otsi ntsoleha woka = Though I have not eaten I will go. [Directional Prefixes.] Certain prefixes are added to verbs of motion to indicate direction. (1) chung = “up”; chungwoka = I will go up. (2) cho = “down”; chowoka = I will go down. (3) thre or thro = “in”; threyia = come in. throwoa = go in. (4) chi = “out”; chiyia = go out. [Conditional Clauses.] A conditional clause is usually expressed participially by means of the postposition -na added to the verbal stem. Another method is to add -wo to the verbal root of the protasis and -katola to the verbal root of the apodosis. Otsi hello liwo ana tsokatola [226] = If rice were here I would eat. [Purpose.] Purpose is usually expressed by adding the postposition -lo, “to,” to the verbal root. It may also be expressed by the prefix e-, either with or without the postposition -lo, or by the suffix kiatto. Ana tsolo rōcho. } Ana etsolo rocho. } I came to eat. Ana etso rocho. } Ana tsokiatto rocho. } [Negative.] With the imperative the prohibitive prefix tī- is used. Titsoa = Do not eat. In the other tenses n (or sometimes for euphony m) is prefixed to the verb. Ana ntso = I do not eat. [Interrogatives.] The following suffixes are added to the verbal root plus the termination -a. (1) -ke. Nno tsoake = Do you eat? (2) -nūng. Nno tsoanung = Do you eat? (3) -la, with a reduplicated verbal root. Nna tsotsoala = Do you eat? (4) -ela, with a reduplicated verbal root. This form is only used when speaking of past time. The termination -a of the verbal root is elided and disappears. Nno tsotsoela = Did you eat? (5) For double questions -lo is suffixed to the affirmative verb and -la (or -ela) to the negative verb. Nno tsoalo ntsoala = Do you eat or not? (6) -ne is used in asking permission. Ana tsoane = May I eat? [Voice.] There is no passive form of the verb. I have eaten up my rice = ana atsi tsochaka. My rice has been eaten up = atsi tsochaka. The latter appears to be really a case in which the subject is understood. [Verbal Synonyms.] As in other Naga languages, different verbs are used for variations of the same act. Dr. Witter gives the following list as an example. Ephyopala = to wash in general. Etsiala = ,,  ,,  clothes. Süala = ,,  ,,  dishes. Myuala = ,,  ,,  face. Phiala = ,,  ,,  feet. Ntsakala = ,,  ,,  hands. [Adverbs.] The following are typical examples. Many are composite words formed from a noun or pronoun and a postposition.
