Southern French clan dancing at end of show (9)
I believe the answer is:
provencal
'southern french' is the definition.
'Provencal' can be an answer for 'french' (Provencal is an example). I am unsure of the 'southern' bit.
'clan dancing at end of show' is the wordplay.
'dancing' indicates anagramming the letters.
'at end of' is a charade indicator (letters next to each other) (some letters go at the end of others).
'show' becomes 'prove' (proving is a kind of showing).
'clan' with letters rearranged gives 'ncal'.
'ncal' put after 'prove' is 'PROVENCAL'.
Can you help me to learn more?
(Other definitions for provencal that I've seen before include "French region" , "Of the region in south-eastern France" , "of Langue d'oc" , "Language in France" , "French language" .)
