The look of a light-hearted lad who's lost a lot (6)
I believe the answer is:
glance
'the look' is the definition.
(glance is a kind of look)
'a light-hearted lad who's lost a lot' is the wordplay.
I cannot quite understand how this works, but
'a' could be 'an' and 'an' is present in the answer.
'lost' could be 'l' (abbreviation in sporting league tables) and 'l' is located in the answer.
'lot' could be 'c' and 'c' is found in the answer.
The remaining letters 'ge' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for glance that I've seen before include "Batsman's stroke" , "Look quickly at -- cricket stroke" , "Take a quick look" , "deflection" , "A brief or casual look" .)
