Erlewine, Michael Yoshitaka, 2015. “Minimality and focus-sensitive adverb placement.”
Proceedings of NELS 45, volume 1, pages 193–202.

In this paper I discuss the distribution of focus-sensitive adverbs in Vietnamese, which exhibits a Minimality effect. Given a fixed position for focus β, there may be different structural heights within a given phase where an adverb α associating with that focus β can adjoin. The focus-sensitive adverb α must appear in the position which minimizes the structural distance between it and its focus associate β. This translates into a requirement that focus-sensitive adverbs adjoin as low as possible, within a particular set of possible adjunction positions.

Much previous literature on Minimality has focused on whether or not such effects derive from transderivational competition, based primarily on Minimality effects on movement. I show that previous approaches to well-studied Minimality patterns which avoid transderivational competition do not extend to the pattern observed here. In contrast, we can develop a uniform treatment of Minimality effects if we adopt transderivational competition as in early Minimalist work such as Chomsky (1992).
