Declare in doubtful taste (5)
I believe the answer is:
state
'declare' is the definition.
(thesaurus)
'doubtful taste' is the wordplay.
'doubtful' indicates anagramming the letters.
'taste' anagrammed gives 'STATE'.
'in' acts as a link.
(Other definitions for state that I've seen before include "Say; nation" , "Specify condition" , "Declare: condition" , "E.g. Georgia" , "Speak" .)
