Etymology

The noun is inherited from Middle English cost, borrowed from Old French cost (“cost, outlay; hardship”) (also coust, modern coût),[2][3][4] from the verb coster (“to cost”),[3][5][6] which comes from Latin cōnstāre (“to stand together, stand firm, be fixed; to stand at a price”),[3][2][7] through a Romance form *costāre.[8][4] Latin cōnstāre is formed from con- (“together”) and stāre (“to stand”),[3][2] which Etymonline traces to Proto-Indo-European *sta- (“to stand, be firm”).[2] Etymonline compares the modern idiom of a thing that “stands at” a price.[2] The English verb is inherited from Middle English costen, from Old French coster.[3][5] Barnhart notes that the word spread through the Romance languages (Spanish costar, Italian costare) and was widely borrowed into Germanic, Slavic and Celtic.[3][6] It is related to constant, stand and state.[6][7]

Earliest recorded meaning

Price, value: about 1200,[2][3] or before 1300 according to the OED, for what must be given to obtain something.[9]

Semantic evolution

The sense “outlay of money, expenditure” is from about 1300[2] or 1386.[9] Expenses of litigation have been costs since 1340,[9][10] and expenditure of time or labour, or what is lost in gaining something, is from about 1300.[9] At one's cost is from 1297.[9] The verb meant “to buy” in Cursor Mundi,[3] and “to involve great expenditure” about 1378, in a version of Piers Plowman;[3] “to be the price of” is from the late 14th century.[2][9] “To cause to lose or suffer”, with a personal object, is from 1377.[9] Cost the earth and cost money are from 1667.[9] The original price of a thing (at cost) is from 1873,[9] and cost of living from 1896.[9] The verb “to estimate the cost of”, with the past tense costed, is a later development.[4]
