Praise cold, ignorant lout, worried about answer (14)
I believe the answer is:
congratulation
'praise' is the definition.
(thesaurus)
'cold ignorant lout worried about answer' is the wordplay.
'cold' becomes 'C' (eg on taps).
'worried' indicates an anagram (worry can mean to interfere with or disturb).
'about' is an insertion indicator.
'answer' becomes 'a' (abbreviation eg in Q and A).
'c'+'ignorant'+'lout'='cignorantlout'
'cignorantlout' anagrammed gives 'congrtulation'.
'congrtulation' placed around 'a' is 'CONGRATULATION'.
(Another definition for congratulation that I've seen is " The act of praising".)
