Separate - that's abundantly clear (8)
I believe the answer is:
distinct
This might be a double definition.
'separate' is the first definition.
(synonyms)
'abundantly clear' is the second definition.
'distinct' can be an answer for 'clear' (synonyms). I am unsure of the 'abundantly' bit.
'that's' is the link.
Can you help me to learn more?
(Other definitions for distinct that I've seen before include "Quite clear and defined" , "Discrete, clear-cut" , "Clear and separate from others" , "Well-defined and clear" , "Obvious" .)
