lagjan "to lay, put, place"), causative of
lie (v.2). Meaning "way in which something is laid" (
lay of the land) first recorded 1819. Meaning "have sex with" first recorded 1934, in U.S. slang, from sense of "deposit" (which was in O.E., as in
lay an egg, lay a bet, etc.), perhaps reinforced by
to lie with, a frequent phrase 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.
Lay off "dismiss" (an employee) is from 1868; meaning "stop disturbing" is from 1908. To
lay for (someone) "await a chance at revenge" is from 1494;
lay low "stay inconspicuous" is from 1839. To
lay (someone) low preserves the secondary O.E. sense.
Layabout "habitual loafer" is attested from 1932.
Layup, the basketball shot, is attested from 1948.
