Pronunciation

  • IPA: /ˈen.dʒɪn/[1]

Etymology

It is inherited from Middle English engyn,[2][3] borrowed from Old French engin (“skill, cleverness; trick; war machine”),[4][2] from Latin ingenium (“inborn qualities, talent”),[4][2] in Late Latin also “a war engine, battering ram”,[4] literally “that which is inborn”, from in- (“in”) and the root of gignere (“to beget, produce”),[4][2] from Proto-Indo-European *gene- (“to give birth, beget”).[4] It is related to ingenious.[2][5]

Earliest recorded meaning

A mechanical device, especially one used in war: probably before 1300, in Kyng Alisaunder,[2] and about 1300 in Etymonline.[4] Also about 1300, it meant skill, cleverness, trickery.[2][4]

Semantic evolution

The original senses were ingenuity and cunning, and native wit or genius,[5][6] which survives in Scots as ingine.[5][7] From these came the product of ingenuity, a plot or snare, and also a tool or weapon, especially a large war machine such as a battering ram.[5][8] The broad sense “machine” survives in fire engine and engine of destruction.[2] The sense “a machine that converts energy into mechanical power” emerged in the 18th century,[4] first in compounds such as steam engine (1751) and internal combustion engine (1884),[2] and in the 19th century the word was used especially of steam engines.[4] Engineer is first a builder of military engines, before 1338.[2]
