Cookie Monster Grammar

"Me go to store, get cookie." -- Sesame Street's Cookie Monster

   The perpendicular pronoun no longer stands tall in popular usage. Pronouns in the objective case have taken charge.
   As a result, we hear so-called professional users of the language on television news broadcasts say things like, "Me and him went to the scene ..."
   The preferred phrasing is "He and I" when referring to two people. The same broadcasters have no problem saying, "I went ..." and "He went ..." but when paired, the pronouns leave the subjective, or nominative case and stumble into the objective.
   It's understandable that few students know much about this grammatical field, because the case system no longer exists in English language, with one exception -- pronouns.
   What is the case system? It's when a word changes its form according to its function in a sentence. And while some languages have four or more sets of endings -- nominative, genitive, dative and accusative, for example -- the English language has none. With the exception of pronouns.
   Otherwise, grammar school teachers some 50 years ago inflicted the above four terms on unsuspecting students to describe the case system.  Example: The man, of the man, to the man, for the man. Notice that the relevant noun "man" does not change. With pronouns, however, the terms are I, me, mine; he/she, him/her; his/hers. The word changes its form according to its function.
   Other than the pronoun set, the English language dropped this system centuries ago as it evolved to an amalgamation of Anglo-Saxon, Norman French, Celtic and Danish as well as Latin and Greek.
   Several others in the Romance language group -- French, Spanish, Italian and Portuguese, for example -- also dropped the case system, again with the exception of the pronoun sets.
   The point to remember is that while language constantly changes, with new words and phrases added yearly, if not monthly, there are standards that help to facilitate communication. And that remains the purpose of language -- communication, because if the reader or listener does not understand what you write or say, you have failed to communicate.
