One used to snare girl with love (5)
I believe the answer is:
lasso
'one used to snare' is the definition.
I can't tell whether this definition defines the answer.
'girl with love' is the wordplay.
'girl' becomes 'lass' (lass can informally mean a girl).
'with' is a charade indicator (letters next to each other).
'love' becomes 'o' (love means zero in tennis).
'lass'+'o'='LASSO'
Can you help me to learn more?
(Other definitions for lasso that I've seen before include "Nosed rope" , "Rope with noose for catching animals" , "Rope used for catching cattle" , "Cattle-catching rope" , "One may be caught by this" .)
