It seems like that into the sentence
I cooked the dinner for me myself
I need to insert another myself
because the actor and the receiver of the action is the same person (me).
But in such a case the sentence becomes weird
I cooked the dinner for myself myself
Is it right to say it that way?
Best Answer
Myself comes in two forms:
Reflexive, where it is necessary for the meaning of the sentence: I like myself.
Intensive, where it is added for emphasis: I, myself, did the chores.
Here you are attempting to use it in both its forms. I suggest you remove the intensive myself and keep only the reflexive form: I cooked inner for myself.
The other myself is inferred.
