Lordly lad capturing the heart of a girl (5)
I believe the answer is:
laird
'lordly lad capturing the heart of a girl' is the definition.
I can't judge whether this definition defines the answer.
'lad capturing the heart of a girl' is the wordplay.
'capturing' indicates putting letters inside.
'the heart of' means to look at the middle letters.
The middle letters of 'girl' are 'ir'.
'lad' placed around 'ir' is 'LAIRD'.
Can you help me to learn more?
(Other definitions for laird that I've seen before include "Scottish owner of large estate" , "Estate landowner" , "Scots landowner" , "Scots estate owner" , "rich Scotsman" .)
