Where Scots have to pay out for a piece of land (7)
I believe the answer is:
paisley
'piece of land' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'where scots have to pay out' is the wordplay.
'where scots have' becomes 'isle' (I can't justify this - if you can you should believe this answer much more).
'out' means one lot of letters goes inside another.
'isle' inserted inside 'pay' is 'PAISLEY'.
'for a' acts as a link.
Can you help me to learn more?
(Other definitions for paisley that I've seen before include "Colourful pattern of the northern politician" , "Patterned textile originating in a Scottish town" , "Patterned fabric" , "Colourful Scottish pattern" , "Scottish fabric pattern" .)
