"Ni äter en måltid."

Translation: You are eating a meal.

OMG NO

I accidentally put "You eat a child."

[GlassBlueBird]

I thought 'du' was 'you'. ???

It is, when addressing an individual. "Ni" is how you would address multiple people or a plurality. Kind of like saying "you all". If you were talking to a dating/married couple - and you wanted to ask how they met, you would use "ni" to include both of them in the discussion. It's the "royal you", if you will.

Duolingo is saying "You eat one meal" and using "one" as "en", instead of a.
Unsure if it would accept a, but is it both?

[devalanteriel]

en translates to both. :)

I heard that ni is not often used, or sometimes disrespectful is that true? what should i use?

[devalanteriel]

That's for its usage as a formal singular you - don't use that. :)

But for the general plural you, it's the standard word, nothing weird.

Thank you!
