GA's neighbour with limitless vote for old tax (4)
I believe the answer is:
scot
'old tax' is the definition.
(I've seen this before)
'ga's neighbour with limitless vote' is the wordplay.
'ga's neighbour' becomes 'sc' (I can't justify this - if you can you should believe this answer much more).
'with' says to put letters next to each other.
'limitless' means to look at the middle letters.
The middle letters of 'vote' are 'ot'.
'sc'+'ot'='SCOT'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for scot that I've seen before include "---- free: originally free from penalties of taxation" , "9 [KEIR HARDIE], say" , "One from northern UK" , "Someone from north of the border?" , "levy, once" .)
