"Il te regarde."

Translation: He is looking at you.

[bcrulesok]

"He sees you" ?

[Sitesurf]

"see" = voir

"look at/watch" = regarder.

[salsabeth]

why not ils te regardent?

[Sitesurf]

If you heard the French sentence first, it is correct that "ils te regardent" and "il te regarde" are acceptable because the pronounciation is the same.

[tusharbajaj]

why not il tu regarde

[Sitesurf]

you use "tu" when the pronoun is subject. When it has a function of object, you use "te"
(like I and me in English)

[JoelFeil]

Te is the direct object, right? Is there an easy rule for knowing when that the Dir. Obj. comes before the verb instead of Subj. verb. Dir Obj.?

[Sitesurf]

The 'easy' rule is that object pronouns are always placed before subject and verb (simple or compound):

il te regarde

il t'a regardé(e)
