Proper English

Unlike Standard or Common English which refer to a formal or casual (which can incorporate texting abbreviations etc. and the rules that apply when using them) form respectively, Proper English is different. Many people still don't know that while Standard and Common forms can change based on society's changes, Proper English cannot. Standard and Proper English used to be one and the same, however with major grammatical changes, such as the dropping of "thou" and "thine", Proper English and Standard English split. This is due to the fact that the Proper form is not allowed to change it's grammatical rules, excepting the additions of words where needed. Therefore, Proper English actually refers to Middle English, where these rules for the language were set in place. Standard And Common forms were also one and the same.
