Unreal - table gets broken, then fixed (11)
I believe the answer is:
unalterable
'fixed' is the definition.
(I've seen this in another clue)
'unreal table gets broken' is the wordplay.
'gets broken' indicates an anagram.
'unreal'+'table'='unrealtable'
'unrealtable' with letters rearranged gives 'UNALTERABLE'.
'then' acts as a link.
(Other definitions for unalterable that I've seen before include "Impossible to change" , "Not able to be changed" , "Set in stone" .)
