Recognise, salute (11)
I believe the answer is:
acknowledge
This clue is a double definition.
'recognise' is the first definition.
(synonyms)
'salute' is the second definition.
(thesaurus)
(Other definitions for acknowledge that I've seen before include "Express thanks for" , "Admit - recognise - thank" , "Indicate obligation to" , "Confess" , "Admit the truth of (something)" .)
