Complete degree (4)

I believe the answer is:

rank

This clue is a double definition.

'complete' is the first definition.
(thesaurus)

'degree' is the second definition.
('rank' can be a synonym of 'degree')

(Other definitions for rank that I've seen before include "Utter" , "Complete" , "Foul and disgusting" , "Row, class" , "(Taxi) stand" .)

I've seen this clue in The Telegraph.
