What does bleariest mean?
"Bleariest" is the superlative form of the adjective "bleary", which describes eyes that are dimmed, reddened, or blurred by fatigue, sleeplessness, tears, or heavy drinking. To say someone has "the bleariest eyes" is to place them at the furthest end of that scale — the most exhausted-looking of a group. The word belongs chiefly to informal and literary English, where writers use it for vivid physical characterization: the bleariest commuter on the morning train, the bleariest gambler leaving the casino at sunrise. Its figurative extension to anything seen indistinctly — a bleariest glimpse through fog or a smudged pane — is rarer but attested. Derived ultimately from Middle English "blere", meaning to make watery or dim, it shares ancestry with "blur". Because it is a comparison form, it requires three or more referents; between two, "blearier" is correct.
