The emphatic particle fo‘i in Samoan and its cognate ho‘i in Tahitian and Hawaiian are both general particles used very frequently. In this paper, the distribution of fo‘i and ho‘i in these three languages is examined to show similarity and difference among them. The general particle fo‘i / ho‘i in all of these three languages may appear at the end of a predicate phrase (which can be a verbal predicate, a nominal predicate, an interrogative, a negative, or a conjunction which occurs in the predicate position) or at the end of a non-predicate noun phrase. The general particle fo‘i in Samoan and ho‘i in Hawaiian can appear after a topic noun phrase. The general particle fo‘i in Samoan and ho‘i in Tahitian can occur between a determiner (which can be a demonstrative, a possessive, or a determiner "other") and a noun. Each of these determiners can form a noun phrase without any following noun.
