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 1558. The verb meaning "to turn over (the pages of a book)" is from 1663; the sense of a book page is that in the phrase to turn over a (new) leaf (1577). Leaflet is 1787 as a term in botany; 1867 as a term in printing and publication.
Main Entry: leaf Pronunciation: 'lEf Function: noun : a thin layer or sheet of tissue leaf of the coronary ligament is continuouswith the right leaf of the falciform ligament>
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.
Make a fresh start, change one's conduct or attitude for the better, as in He promised the teacher he would turn over a new leaf and behave himself in class. This expression alludes to turning the page of a book to a new page. [Early 1500s]
