Seems like a lot of answers refer to dictionary definitions that are far more comprehensive than whatever results Google is pushing. I've also seen a few links to RAE publications that I don't seem to be able to follow. (I assume they are behind a paywall of some sort, but it may be something I'm doing wrong.) Also, it would make sense that the most authoritative resources would be in Spanish, but since some of us are trying to learn Spanish ourselves, it would be helpful to have English resources as well. (Assuming they are available.)
What publicly-available resources ought I consult when asking or answering questions here?
