The Free On-line Dictionary of Computing (30 December 2018):
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

4. Trees belong to the owner of the land where they grow, but if the
roots go out of one man's land into that of another, or the branches spread
over the adjoining estates, such roots or branches may be cut off by the
owner of the land into which they thus grow. Rolle's R. 394; 3 Bulst. 198;

5. When the roots grow into the adjoining land, the owner of such land
may lawfully claim a right to hold the tree in common with the owner of the

The Devil's Dictionary (1881-1906):
TREE, n. A tall vegetable intended by nature to serve as a penal
apparatus, though through a miscarriage of justice most trees bear
only a negligible fruit, or none at all. When naturally fruited, the
tree is a beneficient agency of civilization and an important factor
in public morals. In the stern West and the sensitive South its fruit
(white and black respectively) though not eaten, is agreeable to the
public taste and, though not exported, profitable to the general
welfare. That the legitimate relation of the tree to justice was no
discovery of Judge Lynch (who, indeed, conceded it no primacy over the
lamp-post and the bridge-girder) is made plain by the following
passage from Morryster, who antedated him by two centuries:
While in yt londe I was carried to see ye Ghogo tree, whereof
I had hearde moch talk; but sayynge yt I saw naught remarkabyll in
it, ye hed manne of ye villayge where it grewe made answer as
"Ye tree is not nowe in fruite, but in his seasonne you shall
see dependynge fr. his braunches all soch as have affroynted ye
King his Majesty."
And I was furder tolde yt ye worde "Ghogo" sygnifyeth in yr
tong ye same as "rapscal" in our owne.
