Clothing found in Durham river (4)
I believe the answer is:
wear
I believe this is a double definition.
'clothing' is the first definition.
(synonyms)
'durham river' is the second definition.
(I've seen this before)
'found in' acts as a link.
(Other definitions for wear that I've seen before include "___ and tear" , "North-east flower" , "Clothing; degrade" , "Durham river" , "Durham's river - erosion" .)
