Word Origin and History for layer
n.

late 14c., "one who or that lays" (especially stones, "a mason"), agent noun from lay (v.). Passive sense of "that which is laid over a surface" first recorded 1610s, but because earliest English use was in cookery, this is perhaps from French liue "binding," used of a thickened sauce. Layer cake attested from 1881.

v.

1832, from layer (n.). Related: Layered; layering.

lay

v.

Old English lecgan "to place on the ground (or other surface)," also "put down (often by striking)," from Proto-Germanic *lagjanan (cf. Old Saxon leggian, Old Norse leggja, Old Frisian ledza, Middle Dutch legghan, Dutch leggen, Old High German lecken, German legen, Gothic lagjan "to lay, put, place"), causative of lie (v.2). As a noun, from 1550s, "act of laying." Meaning "way in which something is laid" (e.g. lay of the land) first recorded 1819.

Meaning "have sex with" first recorded 1934, in U.S. slang, probably from sense of "deposit" (which was in Old English, as in lay an egg, lay a bet, etc.), perhaps reinforced by to lie with, a phrase frequently met in the Bible. The noun meaning "woman available for sexual intercourse" is attested from 1930, but there are suggestions of it in stage puns from as far back as 1767. To lay for (someone) "await a chance at revenge" is from late 15c.; lay low "stay inconspicuous" is from 1839. To lay (someone) low preserves the secondary Old English sense.

adj.

"uneducated; non-clerical," early 14c., from Old French lai "secular, not of the clergy" (Modern French laïque), from Late Latin laicus, from Greek laikos "of the people," from laos "people," of unknown origin. In Middle English, contrasted with learned, a sense revived 1810 for "non-expert."

n.

"short song," mid-13c., from Old French lai "song, lyric," of unknown origin, perhaps from Celtic (cf. Irish laid "song, poem," Gaelic laoidh "poem, verse, play") because the earliest verses so called were Arthurian ballads, but OED finds this "out of the question" and prefers a theory which traces it to a Germanic source, cf. Old High German leich "play, melody, song."

layer in Medicine

layer lay·er (lā'ər)
n.
A single thickness of a material covering a surface or forming an overlying part or segment. v. lay·ered, lay·er·ing, lay·ers

lay

in medieval French literature, a short romance, usually written in octosyllabic verse, that dealt with subjects thought to be of Celtic origin. The earliest lay narratives were written in the 12th century by Marie De France; her works were largely based on earlier Breton versions thought to have been derived from Celtic legend. The Breton lay, a 14th-century English poetic form based on these lays, is exemplified by "The Franklin's Tale" in Geoffrey Chaucer's The Canterbury Tales
