Definition

noun

(1) The normal tendency or the consistent preference for use of one side of the body or of one of a pair of bodily organs.

(2) The dominance or the superior development of one side of the body.


Supplement

Since the body has two distinct sides, it is a normal tendency for a person to use one side more often than the other. There is a palpable preference for use of one eye, ear, hand, foot, as well as brain hemisphere over the other. Hence, terms such as left-handed and right-handed are contrived, as well as left-brained and right-brained.
