Etymology

It is the noun use of the phrasal verb bail out,[2][3][4] formed from English bail + out.[5][6] The sources differ on which verb it contains.[6][4] The OED derives the sense of rescue from difficulty from the legal verb, to obtain a person's release by giving bail, and the parachute sense from the verb meaning to scoop water out of a boat, also spelled bale, perhaps influenced by the legal one.[6][3] Etymonline takes the noun from the aviation use and finds it unclear which sense lies behind the financial one.[4] The legal verb goes back to Old French baillier (“to control, guard; to hand over, deliver”),[4][6] from Latin bāiulō (“to carry a burden”).[4][6] The water-scooping verb comes from an older noun meaning a small bucket, from the French nautical word baille (“bucket”),[4][6] which Etymonline traces to the same Latin verb and the OED, probably, to Late Latin bacula, a diminutive of baca.[4][6] The OED thinks the parachute verb probably a use of either bale, as if letting a bundle through a trapdoor, or of the water-scooping verb, the spelling history favouring the second.[6]

Earliest recorded meaning

A means of release or rescue from difficulty: 1939, in a heading in Time magazine.[6] Merriam-Webster's first date, for an emergency parachute jump from an aircraft, is 1943,[5] Etymonline dates the aviation noun to 1945,[4] and the OED's first record of the parachute sense is from 1955.[6] Dictionary.com dates the word to 1950–55.[2]

Semantic evolution

The phrasal verb bail out, to leave suddenly, is recorded from 1930, first of pilots jumping from aeroplanes;[4] Green's Dictionary of Slang has bale out, to run off or escape from a difficult situation, from 1899–1900, in American use.[7] The noun followed in both uses: an emergency descent by parachute, and the rescue of a person or organization from trouble.[3][5] Etymonline dates the sense "federal help for a private business in trouble" to 1968,[4] and the Shorter Oxford dates the sense of release from financial difficulty to the late 20th century.[3] In current use it is chiefly financial help given to a failing business or economy to save it from collapse.[8][6]
