1. Words produced by the use of all of the letters from a term which, in turn, form the first letter of each new word: An example of an acrogram is the use of the word “dare” to form four new words each beginning with the letters “d”, “a”, “r”, and “e”.

An acrogram can be further exemplified by the use of the letters of a word as a basis for forming lines of poetry or lines in a song, etc. by referring to each of the letters of the base word.
