A jumper for the captain? (7)
I believe the answer is:
skipper
This clue might be a double definition.
'a jumper' is the first definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'captain?' is the second definition.
('skipper' can be a synonym of 'captain')
'for the' is the link.
Can you help me to learn more?
(Other definitions for skipper that I've seen before include "team leader" , "Captain - one using a rope" , "girl with rope?" , "being in charge?" , "Senior pilot" .)
