Treat all these as a capital (11)

Ross

I believe the answer is:

tallahassee

'capital' is the definition.
(state capital of Florida)

'treat all these as a' is the wordplay.
'treat' is an anagram indicator.
'all'+'these'+'as'+'a'='alltheseasa'
'alltheseasa' anagrammed gives 'TALLAHASSEE'.

(Other definitions for tallahassee that I've seen before include "A place in Florida" , "US capital" , "Florida's sate capital" , "Florida city" .)

I've seen this clue in The Guardian.
