First attested
a. 1250
Borrowed from

Ultimate origin
Old French (souil)

Etymology

The verb is inherited from Middle English soillen, borrowed from Old French souillier (“to make dirty; originally, to wallow”),[3][2][5] from souil “tub, wild boar's wallow, pigsty”.[3][2] This is either from Latin solium (“tub for bathing, seat”), related to sit,[2][3] or from Latin suculus “little pig” or suile “pigsty”, from sūs (“pig”).[3][5][6] Barnhart says the second view has been superseded by von Wartburg's work in the FEW.[2]

Earliest recorded meaning

To defile or pollute with sin: the early 13th century, before 1250 in the Ancrene Riwle.[3][2]

Semantic evolution

The literal sense, to make dirty on the surface, is attested from about 1300.[3] A noun soil, a muddy place or a wild boar's wallow, and in hunting a pool where a hunted deer takes refuge, is from the early 15th century,[3][6] and filth, refuse or excrement from about 1600, partly as a native formation from the verb.[3] This is the soil of the plumber's soil pipe (by 1833) and of archaic night-soil.[3]

First attested

Borrowed from
Anglo-Norman soil via Middle English
Ultimate origin
Latin (solium)

Etymology

The earth is inherited from Middle English sol, soyle, borrowed from Anglo-Norman soil (“piece of ground, place”),[3][2][5] from Latin solium (“seat”), influenced in meaning by Latin solum “ground, base, floor”.[2][5][7] Etymonline describes it as a merger of three Old French words: sol “ground”, from solum; soeul “threshold, place”, from solium; and soille “a miry place”.[3] It is related to sole and sit.[2][5]

Earliest recorded meaning

Land, an area or place: about 1300 in Etymonline, before 1300 in Barnhart.[3][2]

Semantic evolution

The earth or ground is from the late 14th century,[3] and mould or earth, especially that in which plants grow, from the mid-15th.[3] One's native land, as in foreign soil, is from about 1400, and this was the original sense of the word.[3][1][8]

Timeline

  • c. 1300 – land, place.[3]
  • c. 1400 – one's native land.[3][8]
  • mid-15th century – earth for plants.[3]

Modern meaning

Noun

  1. The top layer of the earth in which plants grow, made of rock particles mixed with humus.
  2. A particular kind of earth: sandy soil.
  3. A country or territory: on foreign soil.
  4. A place where something can grow and develop.
  • solum
  • sully
  • sole

Usage notes

An obsolete verb soil, “to absolve” or “to solve a problem”, from Old French soudre and Latin solvere, was used until the 17th century; compare assoil.[6]
