Modify shrapnel (6)
I believe the answer is:
change
This might be a double definition.
'modify' is the first definition.
(I know that modify is a kind of change)
'shrapnel' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
Can you help me to learn more?
(Other definitions for change that I've seen before include "Word for small coins in pocket" , "Alter the money returned" , "Loose money in pocket" , "Alter with loose coins" , "Transfer" .)
