Harmonization and disharmonization of affix ordering and basic word order.

Cross-category harmony (correlations between basic word order and prefer-ence for suffixes or prefixes) has been proposed by several typologists and psy-cholinguists as a principle to explain some apparent crosslinguistic tendencies. This article attempts to test whether cross-category harmony has an observable influence on morphosyntactic change, and reviews cases of harmonization and disharmonization of affix order. The grammaticalization of associated motion prefixes in Japhug Rgyalrong, a verb-final language of southwest China, con-stitutes a solid case of development of a disharmonie construction out of a harmonic one, and runs counter to the idea that head ordering principles have a direct effect on language change.
