All permutations of S, V and O are possible. No study has been made on the relative frequency of their order. S and O are marked on the verb, not obligatorily as nouns or pronouns, which means that sentences with overt subjects and objects are rare in discourse. Impressionistically, SOV and SVO are most frequent in texts and in elicitation.
