desirability的词源

英文词源

luxury: luxury: [14] Luxury was originally a pejorative word, denoting ‘sinful self-indulgence’. Not until the 17th century did it begin to acquire its positive modern connotations of costliness, comfort, and desirability. It came via Old French from Latin luxuria ‘excess’, a derivative of luxus ‘excess, abundance, extravagance’. The Latin derived verb luxuriāre ‘grow profusely’ has given English luxuriant [16] and luxuriate [17].
need: need: [OE] Need is a widespread Germanic noun, with relatives also in German not, Dutch nood, Swedish nöd, and Danish nød. It comes from a prehistoric Germanic *nauthiz, whose non- Germanic relatives, such as Old Prussian nautin ‘necessity, distress’ and Czech nyti ‘languish’, reveal its darker past, in which the accent was on ‘distress’ and ‘straitened circumstances’ rather than just the desirability of having something (these connotations survive in German not, which means ‘misery, danger, emergency’ as well as ‘need’).
desirable (adj.): late 14c., from Old French desirable (12c.), from dasirer (see desire (v.)). Related: Desirably; desirability.
