I learned this when I was first thinking about starting this blog. I don’t think I’ve done this yet, and I’m going to try to keep it from becoming a habit, but I’m going to skip way ahead to contrast with another word.
A word formed from the initial letters of other words. Hence as v. trans., to convert into an acronym (chiefly pass. and as pa. pple.). Also acronymic a.; acronymically adv.; acronyming vbl. n.; acronymize v. trans.
The use of initials; a significative group of initial letters. Now spec. a group of initial letters used as an abbreviation for a name or expression, each letter or part being pronounced separately (contrasted with ACRONYM).
