Definitions for "Capricious"
Governed or characterized by caprice; apt to change suddenly; freakish; whimsical; changeable.
To be governed by caprice [from the Latin for "hedgehog's head"; think of spiky-haired idlers like Einstein and Sid Vicious] is to give in to one's every fantastic whim, irresponsible vagary, or irrational desire. The true idler knows better than to fill his waking moments with turbulence and hurry but as long as one remains grounded to some extent, capriciousness ought not to be discouraged. See: DESULTORY, DISTRACTED, DIZZY, ECCENTRIC, FLIGHTY.
changeable; "a capricious summer breeze"; "freakish weather"
