Like a playwright's irritation about Sterne novel (11)
I believe the answer is:
pinteresque
'like a playwright's' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'irritation about sterne novel' is the wordplay.
'irritation' becomes 'pique' (synonyms).
'about' indicates putting letters inside.
'novel' indicates an anagram (letters in a new or novel order).
'sterne' anagrammed gives 'nteres'.
'pique' placed around 'nteres' is 'PINTERESQUE'.
Can you help me to learn more?
(Another definition for pinteresque that I've seen is " particularly dramatic style".)
