grasshopper n.

Old English græs, gærs "herb, plant, grass," from Proto-Germanic *grasan (source also of Old Frisian gers "grass, turf, kind of grass," Old Norse, Old Saxon, Dutch, Old High German, German, Gothic gras, Swedish gräs"grass"), which, according to Watkins, is from PIE *ghros- "young shoot, sprout," from root *ghre- "to grow, become green," thus related to grow and green, but not to Latin grāmen "grass, plant, herb." But Boutkan considers grāmen the only reliable cognate and proposes a substrate origin.

As a color name (especially grass-green, Old English græsgrene) by c. 1300. Sense of "marijuana" is recorded by 1932, American English. The grass skirt worn by people native to tropical regions is mentioned by 1874; the warning to keep off the grass by 1843 (in New York City's Central Park). Grass-fed of cattle, etc., (opposed to stall-fed) is from 1774.

"person or animal that hops," mid-13c., agent noun from hop (v.). From c. 1200 as a surname, and perhaps existing in Old English (which had hoppestre "female dancer").
