Catch the wind under one's wings (4)
I believe the answer is:
soar
'catch the wind under one's wings' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for soar that I've seen before include "'Fly, glide (4)'" , "Move quickly upward" , "Fly high, Leicester river" , "Rise high into the air" , "Significant rise" .)
