Comparative: unfunnier
Superlative: unfunniest
Unfunnier → It is formed from the prefix "un-" (meaning not) and the root "funny" (from Old English *funnig*, meaning causing laughter or amusement) combined with the comparative suffix "-er" (meaning more). The word "unfunnier" means not more funny or less funny than something else.
Think of 'not' ('un-') and 'causing laughter' ('funny') — so 'unfunnier' means something that is not more amusing.
