Before you use a word, especially if it has more than one syllable, make sure you know what it means. If you don’t, then you may end up looking as vocabulary-challenged as this writer for Yahoo! Style:
A proprietor is an owner. It makes no sense in this context, even if the writer had used the preposition of instead of to. I haven’t a clue what words the writer should have used since I have no idea what this is supposed to mean. Maybe next time the writer will consult a dictionary before using big words. Nah. That would never happen at Yahoo!.
