Is it grammaticaly correct: "I want you here"?
or should it be said: "I want you to be here"

Question

Answer

I want you + directional particle

Remember "here" has two meanings:
1. Place
I am here. I'm standing here.

2. Direction.
Come here. Move it here.

I want you here. = direction here

Likewise:
I want you there.
I want that table in the corner.
I want you off the roof!
I want you all out of here!

Answer

"I want you here" is perfectly correct: subject-verb-object-location.

Answer

Both are correct.
