Journalists are importunate (5)
I believe the answer is:
press
'journalists' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for press that I've seen before include "Crowd; urge" , "Apply steady force to (something)" , "Push - papers" , "publicity" , "Cupboard for storing clothes" .)
