駄作
ださく · dasaku · JLPT N1 · noun
work
駄 (bad, useless, as in 駄目 dame) + 作 (work, something made) = poor work
駄 means worthless or no good, the same root as 駄目 (dame, no good). 作 means work or something made. Together: a made thing of little value.
作 — person radical 亻 + 乍
作 combines the person radical 亻 with 乍, which originally depicted a sudden action or making something. The character means 'to do, make, or create,' with 亻 indicating human activity and 乍 supplying the sound. Over time it broadened to cover works, deeds, and acting as something.
