Husband has problems stifling camp inclinations (9)
I believe the answer is:
hillsides
'inclinations' is the definition.
(inclined or sloping areas)
'husband has problems stifling camp' is the wordplay.
'husband' becomes 'h'.
'has' says to put letters next to each other.
'problems' becomes 'ills' (I've seen this in another clue).
'stifling' means one lot of letters goes inside another.
'camp' becomes 'side' (both can mean a group or faction).
'ills' placed around 'side' is 'illsides'.
'h'+'illsides'='HILLSIDES'
(Another definition for hillsides that I've seen is " Valley banks".)
