Unacceptable apart from white? (6,3,4)
I believe the answer is:
beyond the pale
'unacceptable' is the definition.
(I've seen this before)
'apart from white?' is the wordplay.
I cannot quite understand how this works, but
'from' could be 'o' (I've seen this in other clues) and 'o' is found in the answer.
'white?' could be 'pale' (I've seen this before) and 'pale' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for beyond the pale that I've seen before include "Not understood by untanned people" , "to be completely colourless?" , "Unthinkable" , "completely washed out?" , "Outside the bounds of acceptable behaviour" .)
