Lived to wed new lieutenant (5)
I believe the answer is:
dwelt
'lived' is the definition.
(I've seen this in another clue)
'wed new lieutenant' is the wordplay.
'new' is an anagram indicator.
'lieutenant' becomes 'lt' (abbreviation for lieutenant).
'wed' is an anagram of 'dwe'.
'dwe'+'lt'='DWELT'
'to' acts as a link.
(Other definitions for dwelt that I've seen before include "Put much stress (on)" , "Spoke at length" , "Thought moodily (about something)" , "Lived in, musically in marbe halls" , "Had house" .)
