Dealt with the problem of the confounded rent? (6)
I believe the answer is:
darned
'confounded rent?' is the definition.
'darned' can be an answer for 'confounded' (I've seen this in another clue). I'm unsure of the 'rent?' bit.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for darned that I've seen before include "Repaired (knitwear)" , "(Of, eg, sock) repaired" , "example of euphemism" , "Repaired (eg, socks)" , "Repaired woollen articles" .)
