hairy

the word 'hairy' is a straightforward english formation from its germanic roots. the core noun 'hair', tracing back to proto-germanic 'khæran', denotes a filament growing from the skin. the adjectival suffix '-y', from proto-germanic '-īgaz', is a prolific english suffix meaning "having the quality of" or "resembling". the literal combination, "full of hair," has been in use since middle english. its informal, abstract sense of "dangerous or frightening" emerged much later, likely in the 19th or early 20th century, drawing a metaphorical link between a perilous situation and the unsettling sensation of something creeping over one's skin.
