I suppose it depends if you count word that came to English directly from Latin or if you count ones of french origin, too.
I'd like to know what it's like for everyday English, not just for what's in the complete Oxford dictionary, because a lot of words come from Latin, that probably aren't used often, but do exist in the Oxford dictionary, if you know what I mean. What you really want to know is how much words of Latin origin you use, isn't it? At least that's what I think is more interesting...
