glossy (adj.)

"glistening smoothness, luster," 1530s, probably from Scandinavian (compare Icelandic glossi "a spark, a flame," related to glossa "to flame"), or obsolete Dutch gloos "a glowing," from Middle High German glos; probably ultimately from the same source as English glow (v.). Superficial lustrous smoothness due to the nature of the material (unlike polish, which is artificial).

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.
