To look at someone with anger or disapproval; a dark, angry expression or look.
From Middle English and possibly Scandinavian origins (related to Old Norse 'glotta,' to grin mockingly). The meaning evolved from mocking grimaces to angry stares.
Glower is one of those perfect English words that describes a very specific feeling—not just angry, but the intense, silent anger shown by staring—Shakespeare used it, and it's just as powerful today!
