Feature includes old rope (5)
I believe the answer is:
noose
'rope' is the definition.
(noose is a kind of rope)
'feature includes old' is the wordplay.
'feature' becomes 'nose' (a facial feature).
'includes' indicates putting letters inside.
'old' becomes 'o' (abbreviation).
'nose' placed around 'o' is 'NOOSE'.
(Other definitions for noose that I've seen before include "Hangman's or cowboy's loop" , "old execution method" , "Sliding loop in a lasso (5)" , "Hanging loop in rope" , "Device for capital punishment" .)
