Quick Summary

An infix is a type of affix, which is a sound or letter attached to or inserted within a word to create a new word or an inflectional form. Unlike prefixes (at the beginning) and suffixes (at the end), infixes are inserted into the middle of a word.123

While infixes are rare in English, they can appear in plural forms, such as the "s" in cupsful or passersby. Some informal infixes can also be used as intensifiers, though these are sometimes referred to as tmesis. Infixes are more common in other languages, including some American Indian languages, Greek, and Tagalog.123
