Change the hose, it’s worn (4)
I believe the answer is:
shoe
'change' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'the hose it's worn' is the wordplay.
'it's worn' indicates anagramming the letters (worn can mean damaged).
'hose' anagrammed gives 'SHOE'.
Can you help me to learn more?
(Other definitions for shoe that I've seen before include "Box for holding and dispensing from pack of cards" , "Slingback, for example" , "Winkle-picker, for example" , "Oxford, for example" , "Sandal, for instance" .)
