blurry (adj.)

1540s, "a moral stain;" c. 1600, "a smear on the surface of writing;" of uncertain origin, perhaps akin to blear. The extended sense of "a confused dimness" is from 1860 [Emerson, in reference to the Orion nebula].

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.
