Crossword Genius

Greatest final (8)

Ross

I believe the answer is:

ultimate

This clue is a double definition.

'greatest' is the first definition.
(thesaurus)

'final' is the second definition.
(similar in meaning)

(Other definitions for ultimate that I've seen before include "Final; fundamental" , "Last or highest" , "Last or concluding element" , "Conclusive" , "Utmost or extreme" .)

I've seen this clue in The Hindu.
