Lived to have drunken, lewd time (5)
I believe the answer is:
dwelt
'lived' is the definition.
(I've seen this before)
'drunken lewd time' is the wordplay.
'drunken' is an anagram indicator.
'time' becomes 't'.
'lewd' with letters rearranged gives 'dwel'.
'dwel'+'t'='DWELT'
'to have' acts as a link.
(Other definitions for dwelt that I've seen before include "was established" , "Persistently thought" , "Spoke at length" , "Had house" , "Lived, resided" .)
