Etymonline
Word Origin & History

lime
"chalky mineral used in making mortar," from O.E. lim "sticky substance, birdlime, mortar," from P.Gmc. *leimaz (cf. O.N. lim, Du. lijm, Ger. Leim), from PIE base *(s)lei- "slime, slimy, sticky" (cf. L. limus "slime, mud, mire," linere "to smear;" O.E. slim "slime;" Skt. linati "adheres to, slips into,
disappears;" Gk. alinein "to anoint, besmear;" O.Ir. leinam "I follow," lit. "I stick to"). Lime is made by putting limestone or shells in a red heat, which burns off the carbonic acid and leaves a brittle white solid which dissolves easily in water. Birdlime is a viscous sticky stuff prepared from holly bark and used to catch small birds.

lime
"type of citrus fruit," 1638, from Sp. lima, from Arabic limah "citrus fruit," a back-formation or a collective noun from limun "lemon" (see lemon).

lime
"linden tree," 1625, from M.E. lynde, from O.E. lind (see linden). The change of -n- to -m- probably began in compounds whose second element began in a labial (e.g. line-bark, line-bast).

Lime definition


The Hebrew word so rendered means "boiling" or "effervescing." From Isa. 33:12 it appears that lime was made in a kiln lighted by thorn-bushes. In Amos 2:1 it is recorded that the king of Moab "burned the bones of the king of Edom into lime." The same Hebrew word is used in Deut. 27:2-4, and is there rendered "plaster." Limestone is the chief constituent of the mountains of Syria.
