The origin of yes–no question particles in the Niuean language

This paper considers data from Niuean, a Polynesian language with VSO word order and an extensive range of grammatical particles. We focus on three question particles, nakai, ka and kia, examining their possible historical origins. In related languages the preferred means of forming a yes–no question is by intonation alone, while in the Polynesian languages that have yes–no question particles, the forms are lexically distinct from those found in Niuean. We argue that the Niuean unmarked question particle nakai is derived from the negative, the pragmatically marked kia construction from the polite form of the imperative, and the ka construction from a lexical item which signals confirmation. In all three cases, the question particles do not replace their original grammatical or lexical source words but rather co-exist with them in new contexts. The three question particles have all undergone a process of semantic bleaching, increased syntactic bonding, and in some cases, phonetic reduction. While two of the processes have occurred early in Niuean, one is a very recent development.
