rash แปลว่า

Probably a variant of race, raze (“to demolish; to destroy, obliterate; to scrape as if with a razor”), possibly modelled after rash (etymology 5 or etymology 6). Raze is derived from Middle English rasen, racen, rase (“to scrape; to shave; to erase; to pull; to strip off; to pluck or tear out; to root out (a tree, etc.); to pull away, snatch; to pull down; to knock down; to rend, tear apart; to pick clean, strip; to cleave, slice; to sever; to lacerate; to pierce; to carve, engrave; to dig; (figuratively) to expunge, obliterate; to alter”) [and other forms], from Anglo-Norman raser, rasere, rasser, Middle French, Old French raser (“to shave; to touch lightly, graze; to level off (grain, etc.) in a measure; to demolish, tear down; to erase; to polish; to wear down”), from Vulgar Latin *raso (“to shave; to scrape; to scratch; to touch lightly, graze”), from Latin rāsus (“scraped; shaved”); see further at etymology 2.
