In case you aren't convinced that there are still a great many differences in American English usage, here are some quizzes to test your knowledge of our language. You have probably not heard of many of the terms or meanings. These are a stretch for most people.
Start with the Synonyms Quiz. Then check the Synonym Quiz Answers. All of these terms are entries or senses of entries in DARE. You might not know those that are not used in your part of the country. Or, since these are fairly common terms, you might know them all.
If you can correctly answer all of the Volume IV Quiz, go to the head of the class!
