More alternative comedians ultimately follow the French (4)
I believe the answer is:
less
'more alternative' is the definition.
(I've seen this in another clue)
'comedians ultimately follow the french' is the wordplay.
'ultimately' indicates one should take the final letters.
'follow' is a charade indicator (letters next to each other).
'the french' becomes 'les' (plural form of 'the' in French).
The final letter of 'comedians' is 's'.
's' after 'les' is 'LESS'.
(Other definitions for less that I've seen before include "Smaller in amout or degree" , "A smaller amount" , "So-called St James" , "Comparative of 'a little'" , "Minus; not so much" .)
