Word Origin & History

soil
early 13c., "to defile or pollute with sin," from O.Fr. souillier "to foul or make dirty," originally "to wallow," from souil "tub, wild boar's wallow, pigsty," either from L. solium "tub for bathing, seat," or from L. suculus "little pig," from sus "pig." Meaning "to make dirty, begrime" is attested
from c.1300. This is the sense of the noun in archaic night-soil.

soil
"the earth or ground," c.1300, from Anglo-Fr. soil "piece of ground, place" (13c.), from L. solium "seat," meaning confused with that of L. solum "soil, ground." Meaning "mould, earth, dirt" (especially that which plants grow in) is attested from c.1440.

soil  [%PREMIUM_LINK%]     (soil)  Pronunciation Key 
The loose top layer of the Earth's surface, consisting of rock and mineral particles mixed with decayed organic matter (humus), and capable of retaining water, providing nutrients for plants, and supporting a wide range of biotic communities. Soil is formed by a combination of depositional, chemical, and biological processes and plays an important role in the carbon, nitrogen, and hydrologic cycles. Soil types vary widely from one region to another, depending on the type of bedrock they overlie and the climate in which they form. In wet and humid regions, for example, soils tend to be thicker than they do in dry regions. See more at A horizon, B horizon, C horizon., See illustration at ABC soil.
