Gramogram

A gramogram, grammagram, or letteral word is a letter or group of letters which can be pronounced to form one or more words, as in "CU" for "see you". They are a subset of rebuses, and are commonly used as abbreviations.

They are sometimes used as a component of cryptic crossword clues.
