Hi Olivier,

The article is in two parts. First, Chris explains the "formal"(standard) use of like, which you would learn in any English course.

The second part has the informal uses, eg. <em>be like</em> = <em>say</em>/<em>think</em>, or <em>like</em> as an interjection. The informal uses are typically American.

do americans tend to use the word Like? that's the reason of the title of the article about speaking like an american?
