Inflammable should mean something is not flammable. Intoxicated should mean one is not drunk. If one is drunk, he would be toxicated. Right? Inclement weather should be good weather, as it implies the weather is not clement. But clement means good or favorable.
Well, if the Old English root is "en," it should be used instead of "in." It would make more sense if inflammable was enflammable; intoxicated was entoxicated and inclement was enclement.
Inflammable should mean something is not flammable.
I like to freely use parenthetical phrases.
You give yourself more than that.
I was glad to learn something I did not previously know, that to speak English correctly one has to have been born somewhere in the US.
Now you are talking about something completely different. English is not one, but many languages. You have American English, British English, Canadian English, Indian English, etc. Besides the differeces in words and expressions, there are various accents, not only amongst the different countries, but within regions of a country. There are also class differences in the way English is spoken.
Last night I was on the phone with a customer service person. He was obviously British (surprise). I had to ask him to speak more slowly, because I could not understand him.
However, I believe, the reason the "world" is learning English today is because the U.S.A speaks American English, not because there is a British English, and Indian English, etc.
I shan't be afraid to give the Yanks credit for promulgating the language.
