late 15c., from Middle French aggravation, from Late Latin aggravationem (nominative aggravatio), noun of action from past participle stem of Latin aggravare “make heavier,” figuratively “to embarrass further, increase in oppressiveness,” from ad “to” (see ad-) + gravare “weigh down,” from gravis “heavy” (see grave (adj.)). Oldest sense is “increasing in gravity or seriousness;” that of “irritation” is from 1610s.
