Note
The sense that keeps widening. John Florio's A Worlde of Words (1598) renders the Italian macanopoietico as "an inginer, an engine-maker," which ties the word to machines. Today it covers any branch of engineering, and the stretch is contested. Ian Bogost's 2015 essay "Programmers: Stop Calling Yourselves Engineers" notes that a startup "hiring engineers" may mean anything from JavaScript programmers to roboticists.

Note
Here the word is closest to its origin: Middle English enginour named one who designed, built or operated military works for attack or defense. Shakespeare's Hamlet gives this sense its lasting idiom, the enginer "hoist with his own petar": the bomb-maker blown up by his own bomb. Early spellings wander freely, from enginer and Ingenor to Engineer in Michael Drayton's "The Battaile of Agincourt" (1627).

A gunner's word now out of use, and easy to misread in older verse as the military builder. George Herbert plays on it in 1633: wit is "an unruly engine, wildly striking / Sometimes a friend, sometimes the engineer," the weapon turning on whoever fires it. Walt Whitman still reaches for it in Leaves of Grass (1855). In modern writing, say gunner or artilleryman.

Origin
The noun comes from Middle English enginour ("one who designs, builds, or operates military machines"), borrowed through Anglo-Norman and Old French forms based on engin ("device, machine, ingenuity, trickery"). Engin itself derives from Latin ingenium ("natural ability, intelligence, skill," and in Medieval Latin "engine"), from in- plus gignere ("to beget, produce"). Later the word was also reinforced by engine plus the suffixes -er and -eer, the latter possibly modelled on French ingénieur and Italian ingegniere. The verb comes from the noun.
