Express in a sharp utterance (3)
I believe the answer is:
put
'express' is the definition.
(I know that put is a more specific form of articulate)
'in a sharp utterance' is the wordplay.
'in' indicates a hidden word.
'PUT' is hidden in the letters of 'sharp utterance'.
(Other definitions for put that I've seen before include "Place, lay" , "Place in a position" , "Place in a location" , "Set (in place)" , "Place; placed" .)
