The list of faults of English speakers contains a number of items that crop up in other languages. The peculiar thing is, these same features of language labeled slovenly, incorrect, and “signs of rusticity” do not get so labeled when they occur in high prestige languages. How is this so? Simple: the high prestige languages have a name for the feature, a special linguistic term used by adepts and mavens in the language and, in fact, to study the language means to learn the term and what it labels, all the while according it the respect its English parallel does not receive. A few examples:
dropping a letter, e.g. the g in ing in running. In Greek, both ancient and modern, the same thing happens with n. However, as it is called “n moveable”, no problem, and, in fact, it just makes Greek even that much more…… oh, classical and special.
slurring sounds together, as in the d of “Did you?” sounding like a j: Didjou. Sanskrit does this so much the letters of the Sanskrit alphabet reflect the merging of sounds but it is called by a Sanskrit name, sandhi, which makes it no slovenly but a mark of the great mind required to speak this classical Indian language.
Reflective of an inability to think clearly, we suppose, is the failure of subject-verb agreement, as in, “The list of the highest scoring students HAVE been posted” (instead of “HAS” for anyone not catching it) or “The number of cars in the parking lot ARE quite high”, etc. When a Roman wrote this sort of thing in classical Latin or Ancient Greek, he got a free pass by calling it “The Law of Attraction”.
Then there is copula deletion, a wonderful invention of the Russians and the Arabs, except when a Black kid says, “She my sister” when it becomes a sign of cognitive deficits.
The double negative in English is universally condemned, referring to the mathematical principle that two negatives make a positive, but when it occurs in Spanish, “No veo nada” = I no see nothing or in Russian, “Ya nichego ne vizhu” = I nothing not see, we suddenly switch to The New Math and it is OK.
