More on "'Bending" Pronoun Case, What is Case?

"Case" of nouns and pronouns indicates their function: 1) subjective case, also called nominative case: the noun or pronoun functions as "doer" or "subject of"; 2) objective case, also called accusative (direct object) or dative (indirect object) of the verb; and 3) possessive, also called genitive, in which instances the noun or pronoun are showing ownership or possession of some sort.

A recent comment to the posting "Bending Beckham's Pronouns" of 7/26/2007, which should be read first, prompts the following response below, also in commentary form suggesting an explanation as to the reasons folks make blunders with their pronouns.

The argument goes that working class folks in England and parts of North America in the nineteenth century would be rightly corrected when putting an object pronoun in a subject position: "Me and Anthony will mop up." Some assert that the problem is mitigated when putting the other party in the compound subject first: "Anthony and I will mop up." That is, a tweaking of the syntax (order or words) will better cue the ear to make the right choice. Probably.
At any rate, if the lesson is presumably "overlearned," folks would then tend to "hyper correct." That is, they would tend to put the subject pronoun anywhere, including in the object position upon merely hearing and then falsely cueing on the word "and": "Anthony told Meg and I."

Makes sense to me.
