Question

I myself saw him do it./
myself​

Answer 1

Answer:

Myself is a reflexive pronoun.

It refers back to the subject of the sentence. Use myself instead of me when the object is the same person as the subject. In other words, use myself when you have already used I in a sentence, but you are still talking about yourself.

Answer 2

Answer:

Myself is a reflexive pronoun.

Explanation:

A reflexive pronoun is a pronoun that refers back to the subject of the clause in which it is used, e.g.They, them,his her,themselves.

A good grammar is the one in which use of same word is avoided  again and again and hence we use reflexive pronoun.

Using myself instead of Me  OR I AM when the object is the same person as the subject sounds more good in grammar.

In other words, using myself when you already used 'I' in a sentence, but you still talk about yourself is a good practice in the grammar
