Display bear (5)
I believe the answer is:
stand
This clue could be a double definition.
'display' is the first definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'bear' is the second definition.
(bear can mean to stand or endure)
Can you help me to learn more?
(Other definitions for stand that I've seen before include "Be upright; base" , "Be likely to rise" , "Set up" , "Remain unaltered, tolerate" , "Decline to interfere when one should?" .)
