These two people got into an argument about language learning*

Basically, I was in a voice room, and there was this one guy who speaks several languages, and this other person who speaks English, learns another language.

Every time the English speaker was trying to understand a new word, the other person would describe it in the target language of the English speaker, and the English speaker would get frustrated.

Like "what does fire mean?"

The other person would describe in the target language: "it's the really hot thing, it's like a gas." And would occasionally send pictures to show.

The english speaker would grow frustrated and say things like "just forget it, ill look it up myself... so it means fire in English." "Yes..." "Ok so you could've just said that."

He said that that's not how languages work

They started becoming condescending to each other and he started doing things on purpose like.

"Ellos estaban tomando vino."

What is vino?

Him "vino means he arrived, or she arrived, or it arrived."

Then he got told he sucks at teaching, and they went nuts and a mutual tantrum ensued, I left the chat room.
