Don't see so much that's immaculate (8)
I believe the answer is:
spotless
'immaculate' is the definition.
(I know that immaculate can be written as spotless)
'don't see so much' is the wordplay.
I cannot quite see how this works, but
'see' could be 'spot' (to spot is to notice or catch sight of) and 'spot' is found in the answer.
The remaining letters 'less' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for spotless that I've seen before include "honest!" , "Free from blemish" , "How Lady Macbeth wanted to be" , "Fully clean" , "Immaculately clean" .)
