Traded in timber at the end of the street (5)
I believe the answer is:
dealt
'traded' is the definition.
(I've seen this in another clue)
'timber at the end of the street' is the wordplay.
'timber' becomes 'deal' (deal is a kind of timber).
'at the end of' indicates one should take the final letters.
The last letter of 'street' is 't'.
'deal'+'t'='DEALT'
'in' acts as a link.
(Other definitions for dealt that I've seen before include "Doled out" , "Traded" , "Handed out (cards)" , "Carried out business" , "Delivered" .)
