Stand to produce (4)
I believe the answer is:
bear
I believe this clue is a double definition.
'stand' is the first definition.
(both can mean to tolerate or endure)
'produce' is the second definition.
(I know that bear is a type of bear)
'to' is the link.
(Other definitions for bear that I've seen before include "Hold up" , "eg Paddington or Yogi" , "It could be polar or grizzly" , "Pessimistic investor" , "Tolerate - carnivore" .)
