Middle English hungry, hungri, from Old English hungrig "hungry, famished;" see hunger (n.) + -y (2). Common West Germanic; compare Old Frisian hungerig, Dutch hongerig, German hungrig. Figurative use from c. 1200. Related: Hungriness.
Old English hunger, hungor "unease or pain caused by lack of food, debility from lack of food, craving appetite," also "famine, scarcity of food in a place," from Proto-Germanic *hungraz (source also of Old Frisian hunger, Old Saxon hungar, Old High German hungar, Old Norse hungr, German hunger, Dutch honger, Gothic huhrus), probably from PIE root *kenk- (2) "to suffer hunger or thirst" (source also of Sanskrit kakate "to thirst;" Lithuanian kanka "pain, ache; torment, affliction;" Greek kagkanos "dry," polykagkes "drying"). From c. 1200 as "a strong or eager desire" (originally spiritual). Hunger strike attested from 1885; earliest references are to prisoners in Russia.
adjective suffix, "full of or characterized by," from Old English -ig, from Proto-Germanic *-iga- (source also of Dutch, Danish, German -ig, Gothic -egs), from PIE -(i)ko-, adjectival suffix, cognate with elements in Greek -ikos, Latin -icus (see -ic). Originally added to nouns in Old English; used from 13c. with verbs, and by 15c. even with other adjectives (for example crispy). Adjectives such as hugy, vasty are artificial words that exist for the sake of poetical metrics.
