Pronunciation

  • /ɪkˈspɛl/[1]

Etymology

It is inherited from Middle English expellen,[2][3][4] borrowed from Latin expellō (“to drive out, drive away”),[5][6][7][8][9] formed from ex- (“out”) and pellō (“to drive, thrust”).[5][6][4][8] Etymonline, after Watkins, traces the verb to Proto-Indo-European *pel- (“to thrust, strike, drive”).[6][4] The OED compares compel, and notes that Old French had espellir and in the 15th century expeller.[5] The same Latin verb gives expulsion and pulse.[8][9][7]

Earliest recorded meaning

Of the body, to cast out matter from within: about 1385, in Chaucer's Knight's Tale,[5][7] which has the form expelle once.[10]

Semantic evolution

In the 15th century the verb was used of driving out enemies and invaders, exorcising the Devil and banishing people from a town or country.[2] The OED's first record for driving a person out of a place is from Caxton in 1490;[5] from 1534 it was used of putting someone out of a society or community.[5] The school sense, making a pupil leave as a punishment, is found in the 1640s by Etymonline;[6] the OED's first record is from 1717, in Defoe.[5] From 1669 the verb was used of a material thing driven out by force, such as a bullet from a gun.[5] Two senses died out: to reject or refuse (1575–1742) and, in Shakespeare's Hamlet, to keep out.[5] Johnson (1755) defined it first as "to drive out; to force away".[11]
