Lark's flight enthralling a daughter (8)
I believe the answer is:
escapade
'lark's' is the definition.
('escapade' can be a synonym of 'lark')
'flight enthralling a daughter' is the wordplay.
'flight' becomes 'escape' ('escape' can be a synonym of 'flight'**).
'enthralling' is an insertion indicator.
'a daughter' becomes 'ad' (I've seen this in other clues).
'escape' placed around 'ad' is 'ESCAPADE'.
(Other definitions for escapade that I've seen before include "Mischievous exploit" , "Caper" , "Adventurous T [TREAT]" , "A reckless or mischievous adventure" , "Adventurous incident" .)
