Girl with old catching rope (5)
I believe the answer is:
lasso
'rope' is the definition.
(I know that lasso is a type of rope)
'girl with old' is the wordplay.
'girl' becomes 'lass' (lass can informally mean a girl).
'with' is a charade indicator (letters next to each other).
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'lass'+'o'='LASSO'
'catching' acts as a link.
(Other definitions for lasso that I've seen before include "Cowboy's rope with sliding noose" , "A cowboy's looped lariat" , "Rope with noose for catching animals" , "Rope used for catching cattle" , "Cow-catching rope?" .)
