What's the "een" in Halloween?
"chalky mineral used in making mortar," from Old English lim "sticky substance, birdlime, mortar, cement, gluten," from Proto-Germanic *leimaz (cf. Old Saxon, Old Norse, Danish lim, Dutch lijm, German Leim "birdlime"), from PIE root *(s)lei- "slime, slimy, sticky" (cf. Latin limus "slime, mud, mire," linere "to smear;" see slime (n.)). 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. Hence lime-kiln (late 13c.), lime-burner (early 14c.). As a verb, c.1200, from the noun.
greenish-yellow citrus fruit, 1630s, probably via Spanish lima, from Arabic limah "citrus fruit," from Persian limun "lemon" (see lemon (n.1)). Related: Limeade (1892), with ending as in lemonade.
"linden tree," 1620s, earlier line (c.1500), from Middle English lynde (early 14c.), from Old English lind "lime tree" (see linden). Klein suggests the change of -n- to -m- probably began in compounds whose second element began in a labial (e.g. line-bark, line-bast). An ornamental European tree unrelated to the tree that produces the citrus fruit.
lime 1 (līm)
A spiny evergreen shrub or tree (Citrus aurantifolia) native to Asia and having leathery leaves, fragrant white flowers, and edible fruit.
The egg-shaped fruit of this plant, having a green rind and acid juice used as flavoring.
Any of various mineral and industrial forms of calcium oxide differing chiefly in water content and percentage of constituents such as silica, alumina, and iron.
See calcium oxide.
A white, lumpy, caustic powder made of calcium oxide sometimes mixed with other chemicals. It is made industrially by heating limestone, bones, or shells. Lime is used as an industrial alkali, in waste treatment, and in making glass, paper, steel, insecticides, and building plaster. It is also added to soil to lower its acidity.
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.
