Courageous Pinter play I'd taken to heart (8)
I believe the answer is:
intrepid
'courageous' is the definition.
(I've seen this in another clue)
'pinter play i'd taken to heart' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'pinter' is 'intrep' which is present in the answer.
'i'd' could be 'id' and 'id' is found in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for intrepid that I've seen before include "I printed this way, being daring" , "without fear" , "Audacious" , "stout" , "Undaunted" .)
