The passive is formed by placing the infix '-w-' before the last vowel of the verb, but it is not frequently used. A 'neutral' voice can be formed by using '-ik-' instead if the preceding vowel is a, i or u, and '-ek-' if the preceding vowel is e or o. This form is differs in meaning from the passive in that it emphasises the state resulting from an action rather than the action itself (cf. English 'the pot is broken', as opposed to 'the ball is kicked').
