All subject-final languages have passive forms of verbs (ones in which the object of the active verb functions as the subject).
Standardized
IF subject full noun phrases follow object full noun phrases, THEN there will be passive forms of verbs.

1. By SUBJECT-FINAL languages Keenan means any language in which full noun phrase subjects must follow noun phrase direct objects in the pragmatically less marked sentence types (which contain both subjects and direct objects) of the language. Sentences which are pragmatically less marked place the fewest restrictions on their contexts of appropriate use. 2. By PASSIVE Keenan understands verb forms in which the object of the active verb functions as the subject. 3a. According to Keenan (#1516), subject-final languages are always verb-initial. This means that Keenan’s claims about subject-final languages can be applied to VOS languages as well. 3b. Cf. a more general claim about verb-initial languages (#1563): Verb-initial languages always have a passive voice and it is almost always marked in the verbal morphology.
