Is "Kunststoff" more commonly used than "Plastik"?
In spoken language, Plastik is more common. Kunststoff is more of a technical or formal term, as far as I can tell.
Thank you. I'd encountered only "Plastik" before, and wondered what was going on.
Is it also more general? As in "synthetic material"?
It may be regional. In the south of Germany I've definitely heard Kunststoff in conversation.
Would Kunststoff literally be "art stuff"?
It sounds to me as well. However, it also means artificial stuff, hence, by extension, plastics
More like artificial material.
The shopping bag choices of the future.
Glass! Always glass.
why is synthetic for Kunstoff wrong according to duo?
"synthetic material" was accepted
Kunst = art stoff = material !!!!
But "Kunst" also means artificial, which is what is meant in this case.
