Tmesis is a literary device that involves separating a word into two parts to insert another word in between them. It is also known as "cutting into." Although not a common term, there are several synonyms for tmesis, including dissected wordplay, splitting, and interjecting. Dissected wordplay is a combination of a word and another sound or word. Splitting refers to the act of dividing the word to insert another word within it. Interjecting means to insert a word into a phrase or sentence for emphasis or stylistic purposes. Tmesis is often used in poetry, humorous writing, and dialogue to create a unique effect on the reader or listener.
