That's a pretty good test of vocabulary. ;o) I've noted that people withough a good grasp will use a word in weird way (like the writer who kept using 'pilgrimaging' and insisted it was ok because it existed in the on-line dictionary as an intransitive verb) and not realize how odd it sounds.

I noticed there are no questions that use prepositions in the blanks, though. (Since different areas use different prepositions, making more than one answer possible). Very interesting.
