• noun money, wealth. This word, spelled in a variety of ways and which was recorded among London schoolchildren in the mid-1990s, is in fact from the much older term ‘(filthy) lucre’ and has been adopted as a vogue term, probably in ignorance of its origin. (Lucre is Middle English from the Latin lucrum, meaning reward or booty.) In American slang ducats is another archaism which has been revived in a similar context.
