Declare the taste to be novel (5)
I believe the answer is:
state
'declare' is the definition.
(I know that state is a type of advise)
'taste to be novel' is the wordplay.
'to be novel' indicates an anagram (letters in a new or novel order).
'taste' is an anagram of 'STATE'.
'the' is the link.
(Other definitions for state that I've seen before include "Pomp; nation" , "Condition; nation" , "Georgia < or Virginia" , "Condition of country." , "Speak" .)
