There are other more reliable signs of the same sort of sloppiness that are independent of native language, which if I were analyzing a bit of documentation I would use. Using inconsistent terminology is probably the biggest one. I struggle with this myself.

It doesn't matter what a "widget" is within your system, but it ought to be one thing and stay that one thing and everything that isn't that thing shouldn't be a "widget". (I'm not even trying to choose a generic word to make a point; I'm literally between two sessions where I'm working on the documentation for my local "widget" concept, which isn't quite like any other widget in the world, most likely.)
