Reach the broken gate at the end of the street (3,2)
I believe the answer is:
get at
'reach' is the definition.
(I know that get at is a kind of reach)
'broken gate at the end of the street' is the wordplay.
'broken' indicates an anagram.
'at the end of' says to take the final letters.
The final letter of 'street' is 't'.
'gate' anagrammed gives 'geta'.
'geta'+'t'='GET AT'
'the' acts as a link.
(Other definitions for get at that I've seen before include "Nobble; gain access to" , "Reach - mean - attack verbally" , "Pick on - gain access to" , "Intend" , "Unfairly influence" .)
