Multiplication stable (4)
I believe the answer is:
stud
This might be a double definition.
'multiplication' is the first definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'stable' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for stud that I've seen before include "Football boot's peg-like projection" , "Boss; item of jewellery" , "Sexual athlete" , "Collar-fastener" , "Jewellery item; horse breeding establishment" .)
