Transposition
Reaching the same position via a different move order than the one usually associated with it.
Transpositions are common between related openings and defenses, and recognizing them helps players apply familiar plans even when the exact move sequence looks unfamiliar.
Etymology
The English noun is attested from the 1530s meaning “removal from one position to another.” The word was then repeatedly borrowed into technical vocabularies: of words and sounds from the 1580s, in music from about 1600, and in algebra from the 1660s — the chess usage belongs to this same family of specialist senses, describing a sequence of moves that arrives at a position also reachable by a different, usually more common, move order. No source consulted gives an etymology, coiner, or earliest documented date for the chess-specific sense.
