grammatical number, singular, plural 1st person, ME, US 2nd person, YOU, Y'ALL 3rd person, HE/SHE/THEY, THEY In spanish we have the distinction naturally: USTED, USTEDES Another example of genuine language tools dismissed as "Incorrect" is African American Vernacular English's "you be", "he be" tense. I don't know the exact distinction, Steven Pinker explains it well. On that note, "that there rooster" is perfecty valid English as well.
