Still agog (10)

I believe the answer is:

breathless

I believe this is a double definition.

'still' is the first definition.
(thesaurus)

'agog' is the second definition.
(thesaurus)

(Other definitions for breathless that I've seen before include "panting?" , "Still" , "Short-winded" , "Spent" , "Gasping for air" .)

I've seen this clue in The Times.
