• Do not confuse an anachronym (such as tin foil) with an anacronym (such as radar or scuba), despite the homophony of the terms.
• Distinguish a retronym, a term invented later for an old object or concept. In a work set before the invention of electric guitars, a reference to an acoustic guitar would be anachronistic, but a reference to one today would not be, although it is a retronym.

• anachronism, retronym
