State an inevitable truth in hearing (6)
I believe the answer is:
assert
'state' is the definition.
(I've seen this in another clue)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for assert that I've seen before include "Declare or affirm" , "State authoritatively" , "Contend, maintain" , "Aver, maintain" , "Declare, profees" .)
