Identified boy embracing beautiful girl (8)
I believe the answer is:
labelled
'identified' is the definition.
(I've seen this before)
'boy embracing beautiful girl' is the wordplay.
'boy' becomes 'lad' (informal term for boy).
'embracing' means one lot of letters goes inside another.
'beautiful girl' becomes 'belle' (belle can mean a beautiful woman).
'lad' placed around 'belle' is 'LABELLED'.
(Other definitions for labelled that I've seen before include "Categorised; tagged" , "Attached a tag to" , "Assigned a category" , "Described" , "Identified" .)
