Tasted peculiar and expressed an opinion (6)
I believe the answer is:
stated
'expressed an opinion' is the definition.
'stated' can be an answer for 'expressed' (stating is a kind of expressing). I'm unsure of the 'an opinion' bit.
'tasted peculiar' is the wordplay.
'peculiar' is an anagram indicator.
'tasted' is an anagram of 'STATED'.
'and' is the link.
Can you help me to learn more?
(Other definitions for stated that I've seen before include "Announced" , "Said firmly, averred" , "Clearly expressed" , "Declared as fact" , "Put in words, said" .)
