Crossword Genius

Deterioration in sport (4)

Ross

I believe the answer is:

wear

This clue is a double definition.

'deterioration' is the first definition.
(wear is a kind of deterioration)

'sport' is the second definition.
(thesaurus)

'in' acts as a link.

(Other definitions for wear that I've seen before include "Dress in; erode" , "Tackle" , "Northern river - sport" , "Tolerate" , "Have on - deteriorate from constant use" .)

I've seen this clue in The Telegraph.
