Noun/Pronoun + “self” pronoun
Incorrect : Alan and myself were present there.
Correct : Alan and I were present there.
Incorrect: Himself was responsible for the accident.
Correct . He himself was responsible for the accident.
Note: ‘Self’ pronouns are not used alone. They are always used with their simple forms. They are used in two ways: (1) for emphasis and (2) reflexively.
For example:
You yourself have done it. (emphatic)
She hurt herself. (reflexive)
In either case, the ‘self’ forms follow their simple forms.
