1. To seize, pull, and tear prey, as a hawk does. Even as an empty eagle, sharp by fast, Tires with her beak on feathers, flesh, and bone. (Shak) Ye dregs of baseness, vultures among men, That tire upon the hearts of generous spirits. (B. Jonson)
2. To seize, rend, or tear something as prey; to be fixed upon, or engaged with, anything. Thus made she her remove, And left wrath tiring on her son. (Chapman) Upon that were my thoughts tiring. (Shak)
Origin: F. Tirer to draw or pull; of Teutonic origin, and akin to E. Tear to rend. See Tirade.
