Can anyone help me with the third answer to G Down. The clue is Cleverest, most acute and I have -C-T---T but just can't get the answer. This is my last answer and it is driving me mad. Many thanks.
The second letter C is already printed in the paper so that is the only one I am certain of. The 4th letter T is from retreat (Fall back, withdraw) and the final T is from assent (acceptance, approval).
