Lived in terribly lewd time (5)
I believe the answer is:
dwelt
'lived in' is the definition.
(I've seen this before)
'terribly lewd time' is the wordplay.
'terribly' indicates an anagram.
'time' becomes 't' (abbreviation).
'lewd' with letters rearranged gives 'dwel'.
'dwel'+'t'='DWELT'
(Other definitions for dwelt that I've seen before include "Thought moodily (about something)" , "Put much stress (on)" , "Lived, resided" , "Remained" , "Inhabited" .)
