"It does not rain."
Translation:Det regnar inte.
'det (pro.) regnar (v.) inte (adv.)' - 'Inte' is an adverb and therefore modifies (negates) the verb, not the pronoun.
Dig is the object pronoun. In english you is both for personal and object pronuon, so that may cause confusion. Du is the subject pronoun, the one who makes the action "You run" = "Du springer " Dig is the object pronoun, the one who "receives" the action "I love you" = "Jag älskar dig" The difference is the same as in I and Me... you wouldn't normally say "Me eat" and you wouldn't normally say "You love I". I hope that is clear enough :)
