Lesson 1.1 extra vocabulary

I would like to draw some conclusions about how to form sentences that are grammatically correct.

Ich komme aus den Vereinigten Staaten.
I come from the United States.

https://dict.leo.org/german-english/the%20United%20States

It looks like “states” is accusative plural, and “the united” is singular masculine accusative. I thought “the united” should agree with the form of the noun “states”?

Please let me know how you would make sense of the correct form of these words to use.

Now thinking I was confused about the grammar of the sentence.

Kommen is an intransitive verb in this sentence. Meaning there is no direct object.

"den Vereinigten Staaten" is all dative plural because this case indicates an indirect object.

Yes, kommen is intransitive, and aus is a preposition that must be followed by the dative case.

Hi Tyler. and sfpugh,

yes,  den Vereinigten Staaten is dative plural as the preposition aus always indicates that the dative case has to be used.

Tschüss

Thanks for the feedback!
