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).
