Probable
Formation
Borrowing
First attested
before 1382, Wycliffe Bible (the verbal noun venting)
Borrowed from
Old French aventer via Middle English
Ultimate origin
Latin ventus

Etymology

The verb is inherited from Middle English venten,[2][3] probably a shortening of aventen,[4][5] borrowed from Old French aventer, a variant of esventer (“to let out, expose to the air”),[5][4][3] from Vulgar Latin *exventō (“to let out air”), formed from ex- (“out”) and ventus (“wind”).[6][3][4] Etymonline traces the Latin noun to Proto-Indo-European *h₂weh₁- (“to blow”), and Ayto notes that it is distantly related to wind.[4][6] The noun comes partly from vent (“wind”) and partly from évent (Old French esvent), a noun formed on that verb,[7][8][9] and partly from the English verb itself.[10] Etymonline adds that it may have merged with the garment word below.[4]

Earliest recorded meaning

Letting something out from a confined space, or giving it an outlet: before 1382, in the verbal noun venting in the Wycliffe Bible.[3] The OED's first example, of giving a wine cask an air hole, is from John Trevisa's translation of Bartholomaeus Anglicus (1398).[7][4]

Semantic evolution

The noun was at first commonly used of the anus,[4] a sense that survives for the cloaca of birds, fish and reptiles;[11][12] the general sense, an opening through which air, smoke or liquid escapes, is also late Middle English.[11] The figurative use belongs to Shakespeare's time: Barnhart dates the sense “to express freely” to The Taming of the Shrew (1596),[3] and the OED records giving vent to an emotion from 1602, in John Marston's Antonio's Revenge;[7] Etymonline links the sense “to divulge, publish” (1590s) to the phrase vent one's spleen.[4] The figurative phrase give vent to follows by 1640, in Philip Massinger.[7] Gunners used vent for the touch-hole of a gun[12] and for windage (1647),[7] and hunters for the surfacing of an otter or beaver to breathe (mid-17th century).[11][5] In geology it is the opening through which a volcano erupts,[12][11] and in Scotland a vent is a chimney, as in J. M. Barrie's Thrums (1889).[13]

First attested
c. 1430, Pilgrimage of the Life of Manhood

Old French fente via Middle English
Ultimate origin
Latin findō

Etymology

It is inherited from Middle English vente, an alteration of fente, borrowed from Old French fente (“slit, cleft”), from fendre (“to split”), from Latin findō (“to cleave, split”).[2][9][8][14] The initial v- is probably due to vent (“wind”).[2][9][8] Etymonline traces the Latin verb to Proto-Indo-European *bʰeyd- (“to split”).[4]

Earliest recorded meaning

A slit in a garment: about 1430, in the Pilgrimage of the Life of Manhood;[7] Merriam-Webster dates it to the 15th century.[2] From 1429 to 1604 the word also meant an opening in a battlement, a crenel.[7][11]

Semantic evolution

Today the word is used above all of the opening at the bottom of the back seam of a coat or jacket, or of a skirt or sleeve.[7][2][11] A verb vent, to trim the slits of a garment, is recorded in 1547 and is now obsolete.[7] The older form fent and this sense lived on in dialect: in Yorkshire, Lancashire and Somerset a vent was the opening at the wrist of a shirt, and a vent-hole its buttonhole.[13] Johnson (1755) derived even the general noun vent, a small aperture, from fente.[15]

Usage notes

The AHD sets vent among verbs for letting thoughts or feelings out: to vent is to unburden oneself of a strong emotion that has been held in, while express covers any communication, in words or not, utter stresses the voice, voice the putting of a view (often a group's) into words, and air the showing of one's opinions, often to show them off.[16]
