Word Origin & History

tree 
O.E. treo, treow "tree" (also "wood"), from P.Gmc. *trewan (cf. O.Fris. tre, O.S. trio, O.N. tre, Goth. triu), from PIE *deru-/*doru- "oak" (cf. Skt. dru "tree, wood," daru "wood, log;" Gk. drys "oak," doru "spear;" O.C.S. drievo "tree, wood;" Serb. drvo "tree," drva "wood;" Rus. drevo "tree, wood;" Czech drva; Pol. drwa "wood;" Lith. derva "pine wood;" O.Ir. daur, Welsh derwen "oak," Albanian drusk "oak"). Importance of the oak in mythology is reflected in the recurring use of words for "oak" to mean "tree." In O.E. and M.E., also "thing made of wood," especially the cross of the Crucifixion and a gallows (cf. Tyburn tree, gallows mentioned 12c. at Tyburn, at junction of Oxford Street and Edgware Road, place of public execution for Middlesex until 1783). Sense in family tree first attested 1706; verb meaning "to chase up a tree" is from 1700. Tree-hugger, contemptuous for "environmentalist" is attested by 1989.
"Minc'd Pyes do not grow upon every tree,
But search the Ovens for them, and there they be."
["Poor Robin," Almanack, 1669]

Computing Dictionary

tree mathematics, data
A directed acyclic graph; i.e. a graph wherein there is only one route between any pair of nodes, and there is a notion of "toward top of the tree" (i.e. the root node), and its opposite direction, toward the leaves. A tree with n nodes has n-1 edges.
Although maybe not part of the widest definition of a tree, a common constraint is that no node can have more than one parent. Moreover, for some applications, it is necessary to consider a node's daughter nodes to be an ordered list, instead of merely a set.
As a data structure in computer programs, trees are used in everything from B-trees in databases and file systems, to game trees in game theory, to syntax trees in a human or computer languages.
