“I am come”, or “I am become”, Grammatically Correct?

 “I am come”, or “I am become”, Are They Grammatically Correct?

They both are wrong. These two sentences don't express your mood properly.

I am come 

This sentence is completely wrong. This sentence express that you are COME. "COME" isn't a noun. It's a verb. If we remove "am" from this sentence we can see this sentence became First Indefinite Tense(Subject + Verb + Object)

N.B: "Am" always indicates yourself not your work.

First Indefinite Tense always expresses your habits. Let's make an example: I come here (It's a habit. You are wanting to express that you come to this place every day. Coming to this place is your habit)

Let's make more examples:

1. I come here every day.

2. I go there every day.

3. I do sum.

I Am Become

This sentence also expresses your feelings in a wrong way. Like before "Become" isn't a noun.  Example: You want to understand the listener that you have become a good person to a bad person.

Now you should say I Became A Good Person Or I Have Became A Good Person. Not I am become a good person.

If we again remove the "Am" from the sentence it's become First Indefinite Tense. It will again express your habits.
