Registers works (5)
I believe the answer is:
tills
This could be a double definition.
'registers' is the first definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps you can see an association between them that I can't see?
'works' is the second definition.
(tilling is a kind of working)
Can you help me to learn more?
(Other definitions for tills that I've seen before include "Ploughs land" , "Cash registers" .)
