Pronunciation

  • /ɪnˈd͡ʒiːnjəs/, /ɪnˈd͡ʒiːni.əs/[1]

Etymology

It is inherited from Middle English ingenious,[2] borrowed from Middle French ingénieux,[3][4][5] whose Old French forms were ingenios and engeignos,[6][5] and partly directly borrowed from Latin ingeniōsus (“of good natural ability, clever”).[5][7][8][9] The OED calls the French origin probable.[5] The Latin adjective comes from ingenium (“inborn quality, natural ability”),[6][3][10] formed from in- (“in”) and the root of gignō (“to beget”),[6][11] from Proto-Indo-European *ǵenh₁- (“to give birth, beget”).[6][12][10] It replaced the older enginous (before 1393), which had been borrowed from the Old French word.[3][6] Latin ingenium is also the source of engine, a doublet,[3][10][7] and of Middle English ingeny (“intellectual capacity, cleverness”).[6]

Earliest recorded meaning

Intelligent, resourceful, sharp-witted: before 1425, in the Middle English translation of Chauliac's surgery, which says that a surgeon must be ingenious.[2][3] The OED's first record is from Caxton's Golden Legend (1483), in the sense "having high intellectual capacity, talented",[5] and Etymonline glosses the early 15th-century sense as "intellectual, talented".[6]

Semantic evolution

Ayto notes that the word began as a more elevated term, "highly intelligent", and by the 16th century was coming down to "cleverly inventive".[10] The general senses "talented, of genius" (1483–1807) and "intelligent, discerning" died out,[5] while "showing cleverness of invention", of things, from 1548, and "clever at contriving or making things", of people, from 1576, became the current use.[5][3][6] Middle English had used enginous for this kind of skill.[6] Johnson (1755) defined it as "witty; inventive; possessed of genius", quoting Shakespeare's Richard III.[13] From the late 16th century its likeness to ingenuous led writers to use it for "noble-minded, frank, candid" (1597–1738), "well born" and, of education, "liberal", all now obsolete;[5][10][9] for the same reason ingenuity, which belongs etymologically to ingenuous, came to mean the quality of being ingenious.[10][3]
