Fix up say to go beyond Scottish island (7)
I believe the answer is:
arrange
'fix' is the definition.
(I've seen this before)
'up say to go beyond scottish island' is the wordplay.
'up' says the letters should be written backwards (in down clue: letters go upwards).
'say' becomes 'eg'.
'to go beyond' means one lot of letters go next to another.
'scottish island' becomes 'arran' (island off the coast of Scotland).
'eg' written backwards gives 'ge'.
'ge' after 'arran' is 'ARRANGE'.
(Other definitions for arrange that I've seen before include "Put in neat order" , "Dispose" , "Put in order; make plans" , "Put in order; plan" , "Set in place" .)
