French region includes an authorised history (10)
I believe the answer is:
provenance
'french region includes an authorised history' is the definition.
I can't judge whether this definition defines the answer.
'french region includes an' is the wordplay.
'french region' becomes 'provence' (I've seen this before).
'includes' is an insertion indicator.
'provence' going around 'an' is 'PROVENANCE'.
Can you help me to learn more?
(Other definitions for provenance that I've seen before include "Origin of" , "Documented history" , "Source of painting" .)
