Prepositions: BELOW & UNDER

Prepositions are hard to master in English. In this lesson, I talk about two very similar prepositions that often cause problems for English learners: "below" and "under". Should you say "He's below 21 years old" or "He's under 21 years old"? Are there situations where you can use both prepositions with no difference in meaning? The answer to the second question is YES, but there are situations where you must choose one or the other. To learn more about the similarities and differences between below and under, watch the video, then do the quiz at to check your understanding. I hope your score won't be below average!
