Love is a noun.It's general.Everyone knows it.
I is a pronoun.I is the subject of the sentence.
Again, love is a verb. We call it a transitive verb.
You is another pronoun. And it is the object of the sentence.
I LOVE YOU is a complete sentence.
I LOVE YOU made the SVO pattern; subject,verb,object.
See,grammar has helped us a lot.
So,I LOVE YOU. ♥
