Reach the broken gate where I’ve left it (3,2)
I believe the answer is:
get at
'reach the broken gate' is the definition.
'get at' can be an answer for 'reach' (getting at is a kind of reaching). I am not sure about the 'the broken gate' bit.
'i've left it' is the wordplay.
'i've left' becomes 'geta' (I can't justify this - if you can you should believe this answer much more).
'it' becomes 't' (abbreviation. e.g. in 'tis).
'geta'+'t'='GET AT'
'where' is the link.
Can you help me to learn more?
(Other definitions for get at that I've seen before include "Reach - mean - attack verbally" , "Pick on - gain access to" , "Unfairly influence" , "Intend" , "Nobble; gain access to" .)
