Manages adequately round a bend in two-door cars (6)
I believe the answer is:
'two-door cars' is the definition.
(I've seen this in another clue)
'manages adequately round a bend' is the wordplay.
'manages adequately' becomes 'copes' ('cope' can be a synonym of 'manage'. I am not sure about the 'adequately' bit.).
'round' is an insertion indicator.
'a bend' becomes 'U' (a U-bend is a kind of bend - pipe under sink).
'copes' enclosing 'u' is 'COUPES'.
'in' acts as a link.
Can you help me to learn more?
