Other forms: shrivelled; shriveled; shrivels; shrivelling; shriveling
When things shrivel, they wrinkle up and get smaller, the way leaves begin to shrivel and turn brown in the fall.
A lack of moisture can cause something to shrivel, and in humans it tends to be the natural process of aging that makes people shrivel a bit. Flowers will shrivel if you forget to water them, and grapes will eventually shrivel into raisins if you dry them out long enough. The root of shrivel is uncertain, but it may have a Scandinavian source and be related to the Swedish word skryvla, "to wrinkle."
