Going up to give a bouquet to (6)
I believe the answer is:
ascent
'going up' is the definition.
(ascending means going up)
'a bouquet to' is the wordplay.
I cannot really understand how this works, but
'a' is within the answer.
'bouquet' could be 'scent' (the scent of a wine) and 'scent' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'to give' is the link.
Can you help me to learn more?
(Other definitions for ascent that I've seen before include "Mountain path" , "Hill" , "A rise in status; climb" , "(A) climb (up mountain)" , "made by Hilary and Tenzing" .)
