Clear and separate from others (8)
I believe the answer is:
distinct
'clear and separate from others' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for distinct that I've seen before include "Individual, separate" , "Readily distinguishable" , "Well-defined and clear" , "Definite and unmistakeable" , "Separate and clear-cut" .)
