Total; not relative (8)
I believe the answer is:
absolute
I believe this clue is a double definition.
'total' is the first definition.
(synonyms)
'not relative' is the second definition.
('absolute' is the opposite to 'relative')
(Other definitions for absolute that I've seen before include "Despotic" , "Complete or unconditional" , "Not qualified or diminished in any way" , "decided" , "Such a ruler is free from all limits" .)
