Phenomenon is singular, phenomena is plural. The same is true for other words of similar form (criterion, etc.). I have an unusual sensitivity to societal grammar, spelling, pronunciation patterns vs the literal rules of language, and only recently has it been clear that most people who use those words use them very consistently incorrectly. This seems to have changed since I was a child. For all the talk about how the Internet's information educates us, we still need to acknowledge that people need to seek out and be receptive to that information.
