Backronym

[1] Many fictional espionage organizations are backronyms, such as SPECTRE (special executive for counterintelligence, terrorism, revenge and extortion) from the James Bond franchise.

Ten years after the initial publication, the backronym APGAR was coined in the US as a mnemonic learning aid: appearance, pulse, grimace, activity, and respiration.

[8] Sometimes a backronym is reputed to have been used in the formation of the original word, and amounts to a false etymology or an urban legend.

[10] The word's actual etymology is unknown, but more likely related to Romani påš xåra ('half-penny') or to Urdu (borrowed from Persian) safed-pōśh ('white robes'), a term for wealthy people.

[15][pages needed] The word Wiki is said to stand for "what I know is",[16] but in fact is derived from the Hawaiian phrase wiki-wiki meaning 'fast'.
