Etymology

It is inherited from Middle English deciden,[2][3] borrowed from Middle French decider,[3][4] and directly from Latin dēcīdere (“to determine; literally, to cut off”),[4][2][5] from dē- (“off”) and caedere (“to cut”),[4][2][6] from Proto-Indo-European *kae-id- (“to strike”).[4] Middle English also had decisen, from the Latin past participle dēcīsus, but deciden displaced it.[2] The idea is of resolving difficulties at a stroke.[4] Latin caedere is also behind concise, excise, precise, scissors and suicide.[6]

Earliest recorded meaning

To settle a dispute or question: about 1380 in the OED,[7] the late 14th century in Etymonline,[4] and before 1393 in Gower's Confessio Amantis in Barnhart.[2]

Semantic evolution

The word was at first used of determining questions, controversies and lawsuits.[7][4] “To bring a person to a decision” is from 1710,[7] and the intransitive “to pronounce a final judgement” from 1732.[7] “To make up one's mind” is from 1830.[4][7] The literal Latin sense “to cut off” was tried in 1579 but did not last.[7] Decided and decidedly are from 1790.[2]
