voluptuous: [14] Voluptuous goes back ultimately to the Indo-European base *wol-, *wel- ‘be pleasing’, which also produced English volunteer and will. From it was descended the Latin adverb volup ‘agreeably’, from which were derived in turn the noun voluptās ‘pleasure’ and the adjective voluptuōsus ‘giving pleasure’. In its transmission via Old French voluptueux to English, it acquired additional connotations of ‘sensual pleasure’. => volition[voluptuous etymology, voluptuous origin, 英语词源]
