Intersentential switching occurs outside the sentence or the clause level (i.e. at sentence or clause boundaries). Intra-sentential switching occurs within a sentence or a clause. Tag-switching is the switching of either a tag phrase or a word, or both, from languageB to language-A, (common intra-sentential switches). Intra-word switching occurs within a word, itself, such as at a morpheme boundary.
