Emily Dickinson Lexicon

MY-SELF', pron.

1. A compound of my and self, used after I, to express emphasis, marking emphatically the distinction between the speaker and another person; as, I myself will do it; I have done it myself.
2. In the objective case, the reciprocal of I. I will defend myself.
3. It is sometimes used without I, particularly in poetry. Myself shall mount the rostrum in his favor. Addison.
