Etymonline

Word Origin & History

leaf

O.E. leaf "leaf of a plant, page of a book," from P.Gmc. *laubaz (cf. O.S. lof, O.N. lauf, O.Fris. laf, Du. loof, O.H.G. loub, Ger. Laub, Goth. lauf), perhaps from PIE *leup- "to peel off, break off" (cf. Lith. luobas, O.C.S. lubu "bark, rind"). Extended 15c. to very thin sheets of metal (esp. gold).

Meaning "hinged flap on the side of a table" is from 1550s. The verb meaning "to turn over (the pages of a book)" is from 1660s; the sense of a book page is that in the phrase to turn over a (new) leaf (1570s).

leave

O.E. læfan "to let remain, remain, bequeath," from P.Gmc. *laibijan (cf. O.Fris. leva "to leave," O.S. farlebid "left over"), causative of *liban "remain," (cf. O.E. belifan, Ger. bleiben, Goth. bileiban "to remain"), from root *laf- "remnant, what remains" (see life,

live), from PIE *lip-/*leip-. The Gmc. root has only the sense "remain, continue," which also is in Gk. lipares "persevering, importunate." But this usually is regarded as a development from the primary PIE sense of "adhere, be sticky" (cf. Lith. lipti, O.C.S. lipet "to adhere," Gk. lipos "grease," Skt. rip-/lip- "to smear, adhere to." Seemingly contradictory meaning of "depart" (early 13c.) comes from notion of "to leave behind" (as in to leave the earth "to die;" to leave the field "retreat").

leave

"permission," O.E. leafe, dat./acc. of leaf "permission," from W.Gmc. *lauba, cognate with O.E. lief "dear," the original idea being "approval resulting from pleasure." See also love, believe. In military sense, it is attested from 1771.

leaf

(lēf) Pronunciation Key

(click for larger image in new window)

An appendage growing from the stem of a plant. Leaves are extremely variable in form and function according to species. For example, the needles of pine trees, the spines of cacti, and the bright red parts of the poinsettia plant are all leaves modified for different purposes. However, most leaves are flat and green and adapted to capturing sunlight and carbon dioxide for photosynthesis. They consist of an outer tissue layer (the epidermis) through which water and gases are exchanged, a spongy inner layer of cells that contain chloroplasts, and veins that supply water and minerals and carry out food. Some leaves are simple, while others are compound, consisting of multiple leaflets. The flat part of the leaf, the blade, is often attached to the stem by a leafstalk.

Leaf definition

of a tree. The olive-leaf mentioned Gen. 8:11. The barren fig-tree had nothing but leaves (Matt. 21:19; Mark 11:13). The oak-leaf is mentioned Isa. 1:30; 6:13. There are numerous allusions to leaves, their flourishing, their decay, and their restoration (Lev. 26:36; Isa. 34:4; Jer. 8:13; Dan. 4:12, 14, 21; Mark 11:13; 13:28). The fresh leaf is a symbol of prosperity (Ps. 1:3; Jer. 17:8; Ezek. 47:12); the faded, of decay (Job 13:25; Isa. 1:30; 64:6; Jer. 8:13). Leaf of a door (1 Kings 6:34), the valve of a folding door. Leaf of a book (Jer. 36:23), perhaps a fold of a roll.
