There are over 1 million words in the English language. But do you know how many prepositions there are? There are less than 150 English prepositions.

Prepositions include Above, About, Around, At, Before, Below, By, For, From, In, Of, Off, On, Over, Since, To, Under and With.

This video looks at two of the most common prepositions in English, In and On, and the different ways they can be used.

For example, do we sit in a chair or on a chair?  We sit in a chair, but we sit on a sofa.

It seems like we should use the same preposition for both situations, because the actions are similar, but that is not the case.

We get in a car, yet we get on a bus, plane or train.  When we exit, we get out of the car, but we get off of the bus, plane or train. Confusing right?

Now a question for you. Where are you now? (Answer using in, on and at.)

If you are a student, you might be at a Miami Beach school on the 1st floor in an English classroom.
