A cape coming up (5)
I believe the answer is:
ahead
This clue might be a double definition.
'a cape coming' is the first definition.
'ahead' can be an answer for 'coming' (I've seen this in another clue). I'm not sure about the 'a cape' bit.
'up' is the second definition.
(similar in meaning)
Can you help me to learn more?
(Other definitions for ahead that I've seen before include "In the leading position" , "Winning" , "In the future" , "in van" , "advanced" .)
