Take the powder back from the clatter (4)
I believe the answer is:
talc
'powder back from the clatter' is the definition.
'talc' can be an answer for 'powder' (talcing is a kind of powdering). I'm not certain of the 'back from the clatter' bit.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for talc that I've seen before include "Powdered mineral" , "Powder used as toiletry" , "White powder for the bathroom" , "In brief, popular body powder" , "Soft stuff" .)
