words that are built with roots from the different languages. Does this make the words "bogus" or is that a common occurrence?

This is not uncommon in and of itself, e.g., television where the tele- is ultimately from the Greek and vision is from the Latin, but with the -phile, -phobe and -mania words you will generally not find it, hearing rather such things as ailurophile rather than felinophile for cat lover.
