1. flare, glitter, flash. 4. See shine1 . 5. Glare, glower, gloat all have connotations of emotion that accompany an intense gaze. To glare is to look piercingly or angrily: A tiger glares at its prey. To glower is to look fiercely and threateningly, as from wrath; it suggests a scowl along with a glare: to glower at a mischievous child. To gloat meant originally to look with exultation, avaricious or malignant, on something or someone: a tyrant gloating over the helplessness of his victim. Today, however, it may simply imply inner exultation.
mid-13c., "shine brightly," perhaps from M.Du., M.L.G. glaren "to gleam," related by rhoticization to glas (see glass). Sense of "stare fiercely" is from c.1600. O.E. glær meant "amber." Glaring "obtrusively conspicuous" is from 1706.
