bleary-eyed

the compound 'bleary-eyed' is a relatively modern formation, built from older english elements. the core term 'blear' is of germanic origin, likely imitative of the action of blurring vision through tears or sleep. the suffix '-y' converts it into an adjective describing a blurred, dim, or watery state. this descriptive term is then combined with 'eyed', a productive suffix in english for creating adjectives denoting physical characteristics. the literal logic is transparent: having eyes that are 'bleary', or blurred from sleep, tears, or exhaustion, which directly conveys the modern meaning of tiredness and unclear vision.
