I'm going to reiterate my stance on this issue, which I recently left in a comment on a question that was similarly debated:
If a English learner is reading a contemporary book or news story, and that learner comes across a word, phrase, or usage they find confusing, and that learner makes a good faith effort to figure out the meaning by consulting a dictionary or other available resources, yet still can't quite put the pieces together, then that question would be an on-topic question, almost by default.
In my opinion, one of the key differentiators between ELL and ELU is that what seems "obvious" to the native speaker cannot be presumed to be "obvious" on ELL. When words have more than one meaning (and, let's face it, most words in English have more than one meaning), we must accept that there may be some built-in ambiguities and confusion that may be hard for the native to understand and grasp. Such missing pieces of the puzzle are what make a question on-topic on ELL, not off-topic.
Before I vote to close as General Reference, I always look in one or two dictionaries first. More than once, I've changed my mind, and opted to answer a question instead of voting to close it, after I've realized a word is being used in way where a dictionary wouldn't be of much help to a confused learner, even if that individual was making an earnest effort to answer their own question through their research.
I've noticed a few questions getting closed recently that I don't think should have been closed. Just because an answer is obvious to you doesn't mean it's obvious to the O.P. Think twice before you vote to close, and even conduct some research of your own, to ensure the dictionary helps make the pictures as clear as you might assume. If a word has six definitions, for example, and Meaning #4 is the one that unlocks the puzzle, are you sure that the novice speaker should or would have enough expertise to focus on that one particular meaning, and eliminate all five of the other alternatives? If not, the question isn't "General Reference."
