A leg is a weight bearing and locomotive structure, usually having a columnar shape. During locomotion, legs function as "extensible struts" - the combination of movements at all joints can be modeled as a single, linear element capable of changing length and rotating about an omnidirectional "hip" joint.
As an anatomical animal structure it is used for locomotion. The distal end is often modified to distribute force (such as a foot). Most animals have an even number of legs.
As a component of furniture it is used for the economy of materials needed to provide the support for the useful surface, the table top or chair seat.

Famous quotes containing the word leg:
“Entrance and exit wounds are silvered clean,
The track aches only when the rain reminds.
The one-legged man forgets his leg of wood.
The one-armed man his jointed wooden arm.
The blinded man sees with his ears and hands
As much or more than once with both his eyes.”
—Robert Graves (1895–1985)
“It is principally for the sake of the leg that a change in the dress of man is so much to be desired.... The leg is the best part of the figure ... and the best leg is the man’s.... Man should no longer disguise the long lines, the strong forms, in those lengths of piping or tubing that are of all garments the most stupid.”
—Alice Meynell (1847–1922)
“Granddaddy used to handle snakes in church. Granny drank strychnine. I guess you could say I had a leg up, genetically speaking.”
—Wesley Strick, U.S. screenwriter, and Martin Scorsese. Max Cady (Robert DeNiro)
