loam

Etymology

It is inherited from Middle English lōm, early and in the north also lam,^[2][3][4] inherited from Old English lām (“clay, mud, mire, earth”),^[5][6][7][8] inherited from Proto-Germanic *laimaz (“mud, loam”).^[7][3][9] It is related to Old Saxon lēmo, Middle Dutch leem, Middle Low German lēm (the source of Lehm) and Old High German leimo.^{[6][3][10][11]} The Germanic forms come from a root meaning "to be sticky", whose other ablaut grades gave lime, birdlime;^[6][12][11] Etymonline and Watkins trace it to Proto-Indo-European *(s)lei- (“slimy”), also the source of slime and of Latin līmus (“mud”).^[7][13][14]

Earliest recorded meaning

Clay, clayey earth or mud, also clay as the material of the human body: Old English, first in glosses, where Bosworth–Toller finds it rendering argilla and līmus.^[6][5] Barnhart dates the Old English word to about 700 and the Middle English lam, moistened clay, to before 1325.^[3]

Semantic evolution

In early use the word was also the stuff from which God made man.^[7][2] The old sense "clay, mud" died out in the 17th century (the OED's last record is from 1657); from before 1400 the word was also used loosely for earth or soil.^[6] From 1480 it named clay moistened into a paste for moulding, plastering walls or making bricks, the sense still used in foundry work.^[6][10][12] The main modern sense, a fertile soil of clay, sand and decayed vegetable matter, is recorded from 1699, in Evelyn's Kalendarium Hortense;^[6][12] Etymonline dates this technical sense to the 1660s.^[7] The verb, to cover or plaster with loam, appears in 1600,^[6][3][7] and in Australia from 1935 it meant to search a hillside for gold by washing the loam at its foot.^[6][14] George Eliot's Adam Bede (1859) gave Loamshire as the name of an imaginary typical rural county.^[7] In Essex dialect the word was used for a stiff, sticky clay, and in Yorkshire the verb was said of the air turning close and heavy.^[15]
