Pronunciation

  • IPA: UK /sləʊp/, US /sloʊp/[1]

Etymology

It is a shortening of aslope, on the incline,[2][3][4] probably from an Old English past participle *āslopen, from āslūpan (“to slip away”),[2][3] from ā- (“away”) and slūpan (“to slip”) (see sleeve).[2][3] Hoad calls aslope of uncertain origin.[4]

Earliest recorded meaning

As an adjective, slanting: 1502 in Barnhart, about 1500 in Etymonline.[2][3]

Semantic evolution

The verb, to go in an oblique direction, is from 1591,[2][3][5] and the noun, an inclination or slant, from 1611, in Cotgrave's dictionary.[2][6][3] A stretch of rising or falling ground is from the 1620s,[3][6] the sense in ski slope.[3] The derogatory American slang use for an East Asian person, from the shape of the eyes, is attested from 1948.[3]
