Many organizations and corporate entities use acronyms as names. Webster's cites SNAFU and RADAR, two terms of World War Two vintage, as examples of acronyms that were created. The word may already exist or it can be a new word. An acronym (pronounced AK-ruh-nihm, from Greek acro- in the sense of extreme or tip and onyma or name) is an abbreviation of several words in such a way that the abbreviation itself forms a pronounceable word.
