An anacronym is an acronym or an abbreviation so old or familiar that no one remembers what its letters stand for, such as BASIC or COBOL . By the way, an acronym is not just any abbreviation. It's a word that is short for other words, usually using their initial letters.
An anagram is a type of word play, the result of rearranging the letters of a word or phrase to produce a new word or phrase, using all the original letters exactly once; for example, the word anagram can be rearranged into nag-a-ram. Someone who creates anagrams may be called an anagrammatist.
