I have to find a man who knows that universal language.

His father was a teacher of German, and he also spoke that language fluently.

"And I bet your mother wouldn't like you using that language."

I asked him in French, whether he understood that language.

But how does one teach that private language between playwright and director?

Armiger, though he heard that language, did not understand it.

They might use long words or speak in another language - until their children learn that language.

"I don't appreciate that language, to be honest with you," she said.

Unfortunately, that language as a living phenomenon is fading fast.

Not that specific language, but I can see how it applies here.
