Occur; take place (9)
I believe the answer is:
transpire
This clue is a double definition.
'occur' is the first definition.
(I know that transpire is a type of occur)
'take place' is the second definition.
(I know that transpire is a type of take place)
(Other definitions for transpire that I've seen before include "Turn out" , "Terrapins (anag)" , "Come to pass" , "Prove to be so, happen" , "Ensue with terrapins" .)
