1774, "to make too small, to pinch or scant," originally in English an adjective, "scant, meager" (1718), possibly from a Scandinavian source (compare Swedish skrumpna "to shrink, shrivel up," Danish skrumpen "shrunken, shriveled," Norwegian dialectal skramp "thin man"), or from a continental Germanic source akin to Middle High German schrimpfen, German schrumpfen "to shrivel" (from Proto-Germanic *skrimp-, from PIE root *(s)kerb- "to turn, bend").
The meaning "economize" is by 1848. Related: Scrimped; scrimping.
-y 2
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.
