Waved when part of grain gets distributed (10)
I believe the answer is:
brandished
'waved' is the definition.
('brandish' can be a synonym of 'wave')
'part of grain gets distributed' is the wordplay.
I cannot quite understand how this works, but
'part' could be 'brand' (brand is a kind of part) and 'brand' is located in the answer.
'gets' could be 'is' (I've seen this in other clues) and 'is' is present in the answer.
The remaining letters 'hed' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'when' is the link.
Can you help me to learn more?
(Other definitions for brandished that I've seen before include "Waved" , "Displayed" .)
