Infixes are morphemes that are inserted into the middle of a word to create new meanings. However, there are many other words that can be used to describe this grammatical feature. Some synonyms for infixes include infixation, infixing, insertions, interfixes, and medial consonants. In some cases, infixes can also be referred to as internal inflection or middle syllable morphemes. These terms are all related to the concept of adding a morpheme to the middle of a word, but each one has a slightly different nuance or focus. Regardless of the terminology used, infixes are a fascinating linguistic feature that can add depth and complexity to language.
