"The artist sells his sculpture."

Translation: Der Künstler verkauft seine Plastik.

[avaschmys]

I've never heard "Plastik" used for "sculpture". Is this a mistake of DL?

[az_p]

No, it's correct.

[Rakascha]

"Plastik" is a valid word in this context. see here: http://www.duden.de/rechtschreibung/Plastik_Skulptur_Anschaulichkeit
But I would more likely use other words anyways.
Like, well, "Skulptur"...., or "Figur" or more general "Werk"

[FreekVerkerk]

"Plastik" is a kind of material. There are artists who make sculptures from wood or metal, or stone. Are they all called "Plastik"? The english word: "sculpture", comes from the verb: "to sculp", something like "basteln". But what is the german name of the product of "basteln"? Eine Plastik?

[Treacle18]

For clarification: die Plastik is sculpture, das Plastik is plastic.

[MatthiasWe907026]

I've read all comments. Even though it is correct connected with art, it is unusual for a normal German to say it in this way. The majority of Germans would say 'Skulptur' instead of 'Plastik'. If you tell that sentence to a normal German, who probably didn't study art, he will in normal case think of normal plastic (Plastik) instead of a sculpture. So even though it is correct, it's unwise to use it while talking to normal people, who are not affiliated with art.

[JanineZillmann]

I've lived in Germany for over 20 years and the german for sculpture is not Plastik!!!

[requin230]

It is a valid translation for sculpture, even if you have not heard it.

[Ray493065]

shouldn't seine be sein (since it is akkusativ and is modifying neuter)

[zengator]

But it's not modifying a neuter noun; it's modifying a feminine noun, die Plastik, meaning "sculpture". The neuter noun, das Plastik, is the material. See Wiktionary, et al.

[Muhammad704143]

I think it would be better to specify his work (artistic sculpture) rather than saying what it's made of.

[zengator]

"Die Plastik" (feminine, which is indicated by the use of seine) means exactly that: "art sculpture".
