Word of reproach for being noisy, that is (3)
I believe the answer is:
fie
'word of reproach' is the definition.
(I've seen this in another clue)
'noisy that is' is the wordplay.
'noisy' becomes 'f' ().
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
'f'+'ie'='FIE'
'for being' acts as a link.
(Other definitions for fie that I've seen before include "Exclamation of mock dismay" , "Shame!" , "Cry of dismay" , "Yuck!" , "Expression of disgust or outrage" .)
