Absolute — out-and-out (4)
I believe the answer is:
rank
I believe this clue is a double definition.
'absolute' is the first definition.
(eg in a phrase like 'rank hypocrisy')
'out-and-out' is the second definition.

(Other definitions for rank that I've seen before include "Row, class" , "degree" , "film executive" , "Foul and disgusting" , "Not qualified to give order" .)
