choosy (adj.)

Old English ceosan "choose, seek out, select from two or more; decide, test, taste, try; accept, approve" (class II strong verb; past tense ceas, past participle coren), from Proto-Germanic *keus- (source also of Old Frisian kiasa, Old Saxon kiosan, Dutch kiezen, Old High German kiosan, German kiesen, Old Norse kjosa, Gothic kiusan "choose," Gothic kausjan "to taste, test"), from PIE root *geus- "to taste; to choose." Only remotely related to choice. Variant spelling chuse is Middle English, very frequent 16c.-18c. The irregular past participle leveled out to chosen by 1200.

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.
