Why no article the before Spanish language in sentences like these

DibShouldn't there be "the" before Spanish and English in the sentence?

No.

The documentary was in Spanish, with English subtitles.

Thanks for the reply

Why not use the since the language and subtitles are specific and we usually use the before languages, for example "there are over a million words in the English language."?

Dibwe usually use the before languages, for example "there are over a million words in the English language."?

The is often used before the word language. If you omitted language you would also have to drop the: There are over a million words in English, not …the English.

We just don’t say The docume

What about cases where you have to make it clear to the listener? Like:

Then I thought you were Russian because you asked me if I've seen some Russian documentary which was in Russian language.

Does it not sound like the above sentence would be incomplete without a "the" at the end?

DibDoes it not sound like the above sentence would be incomplete without a "the" at the end?

It’s incorrect with or without the.

This is correct:

…which was in Russian.

These are not correct:

…which was in Russian language.
…which was in the Russian language.

I meant "language" in the end, not "the". Sorry about that.

So in a nutshell, you are never supposed to say some thing like "this is in German language" and are always supposed to say, "this is in German"?

I was also confused because I've heard native speakers use "language" at the end of sentences like these a couple of times on one of the documentary related message boards tha

Right. Same with *This is in the German language.
