Miss rope? Not entirely (4)
I believe the answer is:
lass
'miss' is the definition.
(lass is a kind of miss)
'rope? not entirely' is the wordplay.
'rope?' becomes 'lasso' (lasso is a kind of rope).
'not entirely' means to remove the last letter.
'lasso' with its last letter removed is 'LASS'.
(Other definitions for lass that I've seen before include "Damsel" , "Young woman, girl" , "Girl (of Richmond Hill?)" , "Scottish girl" , "Familiar form of address for female" .)
