Mountain in France and North America (4)
I believe the answer is:
etna
'mountain' is the definition.
(Etna is an example)
'in france and north america' is the wordplay.
'in france' becomes 'et' (I've seen this in other clues).
'and' is a charade indicator (letters next to each other).
'north america' becomes 'na'.
'et'+'na'='ETNA'
(Other definitions for etna that I've seen before include "Sicilian landmark" , "Volcano in Italy" , "Sicilian hothead?" , "Neat (anag)" , "Volcano in Sicily, quite neat" .)
