Love to support girl that's pulled after a fling? (5)
I believe the answer is:
lasso
'pulled after a fling?' is the definition.
I can't judge whether this defines the answer.
'love to support girl' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'to support' is a charade indicator (letters next to each other) (in a down clue, some letters hold up others).
'girl' becomes 'lass' (lass can informally mean a girl).
'o' put after 'lass' is 'LASSO'.
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for lasso that I've seen before include "Ling-nosed rope" , "Rope with noose for catching animals" , "Cow catcher" , "which may be catching" , "Cattle-catching rope" .)
