Speak English For Heaven's Sake!!!
Here, Here! It's about time this argument was raised, and repeated again and again—seems there are still adherents, even in response to this article. Remember the push to make Jive slang a part of the English language about 40 years ago, or the more recent attempt about 7 years ago to add much from the Ebonics lexicon to the English language. Please...they were very serious about it! And I'm just as serious about how immature and a waste of time that would be!
Heck, I even remember when my one-year younger brother and I, at the ages of four and five, babbled baby talk at each other for hours, merely bonding and/or practicing communication like the adults around us that we tried to emulate. Now, should there be a six year old version of language that we endlessly attempt to decipher, give generic meaning to and add to the English language?
While this isn't really communicating or the same thing as the slang that develops generationally, I don't think we need to! Taken to the extreme, why should I learn French, Russian, Chinese or most common languages of the world to be able to communicate in their native tongue with people in America? (Incidentally for the low-information crowds in America, English is the 'language of the world'!)
What IS true is that the English language will always undergo additions through popular derivations, and hopefully with much forethought and research on the part of established encyclopedic / dictionary publishers—and kept to a sensible minimum. Society can't long endure having 5,000 new dictionary entries released every year before that society raises a collective raised eyebrow and ignores yet another entry into the potpourri of nonsense.
Just as true is the communicative norms that develop within various industries throughout our society, addressing the ever-changing landscape of thought, research and innovation. However, the development of terms in these industries are best kept within the context of the industry they 'grow up' in. For example, how often during the day do you use the phrase, "Boy, Mildred, you're going to give me a myocardial infarction if you keep pestering me!"
Alas, reasonable people will continue to have to correct the less well-informed among us. These days it is primarily high school graduates and drop-outs, and those who tune out of society due to their own shortcomings (disabled) or laziness (low information threshold). To me, the practice and use of the English language, with its rich assortment of evocative, colorful and weighty words and phrases, is as much a joy to use as listening to a good music recording!
Back in the good ole' days of vinyl records, we did not want to get up from our comfy seat and have to move the needle over a deep scratch to keep the record from repeatedly skipping back one track, or have to play it back more than once so that we could better understand the melody being conveyed by a worn-out, popping and scratchy soundtrack—there's enough noise in communication these days!
So, being aware of where an accent originated from, listening attentively to word meaning in slang usage and technical jargon, and asking for clarification will always be with us. However, most high-school graduates and newcomers to this country MUST get in tune with the culture of America and our industrial, societal norms before they start asking America to tune into their baby-talk!
