One of the more striking features in the historical phonology of Palauan is the addition of a velar nasal before word-initial vowels. Because final vowels were unstressed, and almost always disappeared, it is difficult to determine whether a velar nasal would also have been added after final vowels had they been retained. However, a number of loanwords, mostly from Spanish and English, show the addition of a velar nasal after word-final vowels. The change in native vocabulary is exceptionless, while that in loanwords is irregular. Moreover, the two changes appear to be historically disconnected, yet they suggest a common canonical target that persisted over many generations of speakers.
