“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.


  1. A white, caustic, lumpy powder used in analytical and manufacturing procedures, in glassmaking, in waste treatment, in insecticides, and as an industrial alkali.lime2

  1. A white solid compound that has a very high melting point and reacts with water to form calcium hydroxide. It is often prepared commercially by heating limestone. Calcium oxide is used as an alkali for treating acidic soils and in manufacturing steel, paper, and glass, and it is the main component of lime. Chemical formula: CaO.

  1. 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.
