http://dictionary.reference.com/browse/queryLevel of Familiarity: I am familiar with the word in that I have heard it before but because I rarely hear or use the word, it took me a minute to recall its meaning (although it did come to me). I more often hear and am more familiar with the term inquery rather than query.
Should I Know This Word? I think that being familiar with the word is good enough for me. I think that the term inquiry is more often used as a synonym and personally I think it flows better in writing and conversation than query.
Should Others Know This Word? Who and Why? Hmm this one's tough. I don't think it's a word that's crucial to know for most people although those who read higher level texts may see this word more often than someone who is reading middle or secondary school texts. I suppose it's best for the people who are completeing higher level readings to be familiar with this term so that it doesn't impede on their comprehension of the text. Other than that, it's nice to know to "snazz" up your oral and written expressions!
