1.
mediocre work; unremarkable piece
A creative work (book, film, painting, etc.) that is ordinary and lacks distinction. Not necessarily bad, but not noteworthy either.
Usage
凡作 is used primarily in criticism and reviews of creative works. It implies something merely average — not terrible, but lacking in originality or impact. The 凡 character means "ordinary" or "mediocre."
Common collocations
Similar words
傑作 (masterpiece) and 駄作 (terrible work) are at opposite ends of the quality spectrum. 凡作 sits in the middle — better than 駄作 but far from 傑作. 佳作 (commendable work) is slightly above 凡作, indicating decent quality.
