Pinter pretty entertaining to read (9)
I believe the answer is:
interpret
'read' is the definition.
(I know that read is a more specific form of the action interpret)
'pinter pretty entertaining' is the wordplay.
'entertaining' indicates the answer is hidden within the clue.
'INTERPRET' can be found hidden inside 'pinter pretty'.
'to' acts as a link.
(Other definitions for interpret that I've seen before include "Gloss needed" , "Translate into another language" , "Assign one's own meaning to" , "Restate from one language into another" , "Explain the meaning of - another language?" .)
