splashy (adj.)

1736, "water or liquid thrown upon anything," from splash (v.). Meaning "striking or ostentatious display" is first attested 1804. Sense of "small quantity of soda water, etc., added to a drink" is from 1922. Of color or light, 1832.

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.
