They signal the structural relationships that words have to one another and are the glue that holds sentences together. Thus they form important elements in the structures of sentences.

English function words may have fewer than three letters; e.g., 'I', 'an', 'in', while non-function words usually have three or more (e.g., 'eye', 'Ann', 'inn'). The following is a list of the kind of words considered to be function words with English examples. They are all uninflected in English unless marked otherwise: *
