gracile (adj.) Look up gracile at Dictionary.com
1620s, from Latin gracilis "slender, thin, fine; plain, simple." Not etymologically connected to grace but often regarded as if it is. Perhaps a dissimilated form related to Latin cracens "slender;" if so, perhaps cognate with Sanskrit krsah "thin, weak," Avestan keresa- "lean, meager," Lithuanian karštu "to be very old, to age."
