In spoken language, if a name is used to substitute the pronoun I, which is the correct verb to use as the first person?
For example I am Aunt Jalene talking to a kid.
Instead of saying
I try to cook
I said
Aunt Jalene (I as the first person) tries/try to cook.
Should it be try or tries?
You use the third person when writing or speaking about yourself by name and using the name as the subject noun. Indeed, the pronoun to use then becomes he or she too.
As an example, Julius Caesar wrote Commentarii de Bello Gallico (Commentaries on the Gallic War), in which he fought himself. Despite being a biased history, he wrote much of it in the present tense and so it illustrates this point. One part was translated in 1869 as
- ... Caesar, induced by these circumstances, decides that he ought not to wait until the Helvetii, after destroying all the property of his allies, should arrive among the Santones.
It would be the same in spoken English as in "Aunt Jalene thinks that is a bad idea and she is usually correct" rather than "I think that is a bad idea and I am usually correct", since your aim is to get the listeners to think about about what Aunt Jalene's thoughts mean to them.
