Two prohibitives are found. numis (ta-)V and nikara (ta-)V. It is not clear if there is a meaning difference between them. Nikara(ta-) is also used as a habitual negative. The "normal" negators are nuku- unmarked (PRS/PST/NEARFUT) and naa(nda) marked (FUT/VOL/HAB/GENERIC/PREDICTION/CONTRARY TO EXPECTATION/POLITE Q).
