Lived with bad back and skin inflammation (5)
I believe the answer is:
dwelt
'lived' is the definition.
(I've seen this before)
'bad back and skin inflammation' is the wordplay.
'back' suggests the final letters.
'and' is a charade indicator (letters next to each other).
'skin inflammation' becomes 'welt' (I can't explain this - if you can you should give a lot more credence to this answer).
The final letter of 'bad' is 'd'.
'd'+'welt'='DWELT'
'with' is the link.
Can you help me to learn more?
(Other definitions for dwelt that I've seen before include "Spoke at length" , "Remained" , "Had house" , "brooded" , "Lived in, musically in marbe halls" .)
