Lark's flight, gathering wings in abroad (8)
I believe the answer is:
escapade
'lark's' is the definition.
(both can mean an adventure or amusement)
'flight gathering wings in abroad' is the wordplay.
'flight' becomes 'escape' (flight can mean an escape).
'gathering' means one lot of letters goes inside another (gather can mean to acquire or bring in).
'wings in' says to hollow out the word (remove centre letters) (wings can mean the edges of something).
'abroad' with its middle taken out is 'ad'.
'escape' going around 'ad' is 'ESCAPADE'.
(Other definitions for escapade that I've seen before include "A reckless or mischievous adventure" , "Risky venture" , "Madcap adventure" , "Antic" , "Wild prank" .)
