Like captain to finish climb? (6)
I believe the answer is:
ascend
'climb?' is the definition.
(climb can mean to ascend or go up)
'like captain to finish' is the wordplay.
I cannot really understand how this works, but
'like' could be 'as' and 'as' is present in the answer.
'finish' could be 'end' (synonyms) and 'end' is found within the answer.
A single letter 'c' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ascend that I've seen before include "Gain height" , "Travel upwards" , "Gain altitude" , "rise in status" , "Move upward" .)
