Rages about energy lost to cleaning cloths (4)
I believe the answer is:
rags
This might be a double definition.
'rages' is the first definition.
(ragging is a kind of ragging)
'cleaning cloths' is the second definition.
(I've seen this in another clue)
'about energy lost to' acts as a link.
This may not be right. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for rags that I've seen before include "Tatters or university japes" , "Tattered clothing" , "Papers" , "Waste scraps of cloth" , "Tattered cloths" .)
