As per the site rules the "English Language Learners Stack Exchange" is for people who:
teaching English as a foreign language.
According to the descriptions given above, ELL addresses mainly two very different audiences:
1) learners, who are mainly non natives, whose knowledge of the English language may differ considerably.
2) teachers whose knowledge of the language is supposed to be quite good.
Given the wide spectrum of potential users the questions posted on ELL may reasonably vary from simple to quite complex.
I'd like to focus on the lower part of the range, on those "simple" questions that a learner who is still unfamiliar with the English language is expected to ask.
According to the site rules users are supposed to:
make an effort to research their questions before posting it, and be sure to add as much detail as they can when explaining your problem. The more they can tell us, the better answers they'll receive!
Now, in the case of beginners how much basic can questions be to be considered on topic? Is the following question for instance within the site standards? What research should the user present in this case if any?
