The comparative form of 'fruitful,' meaning more productive, successful, or bearing more fruit than something else.
From 'fruit' plus '-ful' (full of) plus '-er' (comparative suffix). This follows standard English adjective formation rules, though 'more fruitful' is more common in modern usage.
English speakers have been debating for centuries whether to say 'fruitfuller' or 'more fruitful'—it's one of those fascinating grammar debates where both are technically correct, but one sounds awkwardly archaic. This mirrors the evolution from Old English's strict inflections to Modern English's preference for phrases.
