And it’s good to be back, lionello, I’ve missed you all too.
I suddenly thought of the word lush for drunkard and wondered if that had any connection with luxury. Nothing in OED to indicate that however. I did learn however that the noun lush originally signified drink as well as drunkard. As for etymology OED simply says ‘of obscure origin, perhaps suggested by lush, adj. 2, on which term there is even less info:
(See quot. 1819.)
1819 J. H. Vaux New Vocab. Flash Lang. in Mem., Lush, or Lushy, drunk.
Even the more familiar lush, adj.1 meaning luxuriant in growth, etc has no etymological connection with luxury. OED tentatively suggests that it is an “[o]nomatopoeic alteration of lash adj. 3.”, with which obscure term I leave you before I get even more befuddled.
