Deteriorated to the west or east (4)

Ross

I believe the answer is:

wore

'deteriorated' is the definition.
(wearing is a kind of deteriorating)

'the west or east' is the wordplay.
'the west' becomes 'W' (abbreviation).
'east' becomes 'e' (abbreviation).
'w'+'or'+'e'='WORE'

'to' acts as a link.

(Other definitions for wore that I've seen before include "Had on (clothes)" , "Was clothed in" , "Sported, put on" , "Eroded" , "Was clad in" .)

I've seen this clue in the Evening Standard.
