sumptuous: [15] Etymologically, sumptuous denotes ‘expensive, costly’; its modern connotations of ‘luxury’ or ‘lavishness’ are a secondary development. It comes via Old French somptueux from Latin sumptuōsus, a derivative of sumptus ‘expense’. This in turn was based on the past participle of the verb sūmere ‘spend, consume, take’ (source also of English assume [15], consume [14], presume [14], resume [15], and subsume [16]). And sūmere in turn was a compound verb, formed from the prefix sub- ‘under’ and emere ‘take’ (source of English example, redeem, etc).
