Prime cheese, foremost from France (5)
I believe the answer is:
brief
'prime' is the definition.
(thesaurus)
'cheese foremost from france' is the wordplay.
'cheese foremost' becomes 'brie' (Brie is an example. I am not sure about the 'foremost' bit.**).
'from' means one lot of letters go next to another.
'france' becomes 'f'.
'brie'+'f'='BRIEF'
Can you help me to learn more?
(Other definitions for brief that I've seen before include "Prime" , "not lasting long" , "brusque > QC, perhaps" , "Barrister (sl.)" , "Short in duration" .)
