If I was a betting man, I'd put my money on the continued devolution of English, but it stays dominant due to mass media (music, video, etc). Yes it apparently continues to add new words every few minutes, but the spoken word had devolved to the point that I can hardly stand to listen to some people.
"Ummm, like, you know, we need to do something about that problem, right?"
"Yea, I was, like, gonna say something dude, but you were all..."
"Right. Like, I mean when I heard about it, it made me angry, you know?"
"An then she was, like, you know"
True stories: I was in a meeting with a guy that used "I mean" and "you know" over 100 times in 15 minutes. One stops listening to the message after being bombarded by those fillers. I have another co-worker that uses the word "essentially" as if he has to hit a quota. I'm not a perfect speaker or snobby by any means (I have my share of umms), but damn.... try to keep it simple and say what you have to say without the filler. Make your 2015 resolution to remove "like (unless comparing two things), you know, right, I mean, you know and stupid ass sayings such as "it is what it is" from your lexicon, unless the phrase is essential (damn... I used it) to the conversation. You'll be a better communicator and people may actually listen to you.
On the lighter side: I have a couple of like minded fellows I work with (with respect to frustrations of verbal English annoyances), and we have a game of reverse bingo going on. Bingo is if you hear a word on your corporate-speak bingo board, you mark it off. Reverse bingo is using an unusual or seldom used word (from a list of mutually agreed upon words) properly in a meeting with witnesses (at least one of the "like minded fellows"). The trick is to have it be a natural part of the conversation as if the word was the right word for the moment. Often the word is a bit obscure/seldom used and sometimes is hard to pronounce (and you catch hell if you screw it up). The funny thing is that though we've busted out words such as tenacious, juxtapose, superfluous, equivocate, analogous (an alternative to using 'like'),surreptitiously and deleterious
As the experiment goes on, we think folks either aren't listening or don't want to say anything to show that they don't understand us. I can say that my listening skills have improved and as such, I still shake my head at what people say versus what they wanted to communicate. One fellow told me he wanted to secularize the data (he meant segregate). Another said they were going to socialize a procedure (socialize isn't used that way). Anyhow, I'll do my part to improve the language in my small land of cubicles.
Have a happy new year, sorry for the long post and happy communicating.
