tmesis

The cutting apart of a word to reveal additional meanings within it. <p>

additional info: (Tmesis appears frequently in contemporary poetry as a way
of increasing the semantic content of a single word. In this way, tmesis works
as a method of visual punning, a common technique of visual poets. Before I
knew the word tmesis (or at least before I thought of it as cutting without
filling), I used my own word for this technique: severlation.)
