"Jeg skriver et brev."

Translation: I am writing a letter.

When you confuse skriver with spiser and it reads "I am eating a letter" Alphabet soup maybe?

[VanNikkel]

Skriver is not only "writing" but "penning" as well?!?

[JasonFries2]

You can write a letter in pencil. To pen requires, well, a pen. They are similar but not the same.

[ScottishScones]

You can write with a pen too...

[Kevin572967]

The translation "I pen one letter" as the answer. More natural sounding English would be I am writing/I write the latter.

I really don't know why that sentence was given as an alternative translation (bad machine learning???) because et can't be translated as "one", only as "a/an". The correct word for the numeral one [1] is ett (for nouns of neuter gender).

As for the verb "to pen", that is a valid translation, but much less common than "writing/writes" and is a consequence of variations in English vocabulary.

[TricksterPocky]

When do you use et or en?

[BouliBouli]

Depends on the gender. Here, letter is neuter so you use "et". For other words (masculine or feminine) you use "en".
Ex: en skogen (a forest)
Et bord (a table)

And just like many languages, you can't guess the gender, you will have to learn it for each word. :)

In the forest, thousands of animals and insects are living. and they all have a gender. I think this is why they use en skogen not et skogen. :)

That's a bit confusing when you think in german. The letter isn't neuter it's masculine so it would be "en brev" , but I think it comes with time to know the gender in norwegian. And that's the fact I love the comments, they help so much
