Smooth things over when dismissed at the club (4,3)
I believe the answer is:
iron out
'smooth things over' is the definition.
'iron out' can be an answer for 'smooth' (I've seen this in another clue). I'm not sure about the 'things over' bit.
'dismissed at the club' is the wordplay.
'dismissed' becomes 'out' (dismissed in cricket).
'at' means one lot of letters go next to another (I've seen this in other clues).
'the club' becomes 'iron' (type of golf club).
'out' after 'iron' is 'IRON OUT'.
'when' acts as a link.
Can you help me to learn more?
(Other definitions for iron out that I've seen before include "Remove (a difficulty)" , "Smooth, clear up" , "ready to make approach?" , "Settle a problem" , "what golfer needs on tee" .)
