 The present is primarily imperfective in meaning and is used for concurrent and future actions as well as past actions with a temporal dimension.The final three finite forms are injunctive where the imperative and the precative together form a paradigm for positive commands and wishes, and the vetitive is used for negative wishes.Additionally the periphrastic prohibitive, formed by the present form of the verb and the negative adverb lā, is used to express negative commands.
