Oh, the glorious world of English grammar! Some days, it is easy; other days, it is very confusing. Hey-ho, that’s just the way it goes. But don’t let this get you down and discourage you from learning, because with practice you’ll master English grammar in no time.

When learning English, one of the things you are introduced to is prepositions. Prepositions are words that are used to tell time, place, direction, location, and spatial relationships of subjects and objects. Some popular prepositions you’ve been using are in, on, and at.

The prepositions in, on, and at are two letter-words that don’t bite. However, they have the ability to cause so much confusion. Nevertheless, these common prepositions play an important role in answering the question of where. Where is the pencil? The pencil is in the pencil case. Where is the cake? The cake is on the table. Where does he work? He works at the hospital.

Furthermore, they also answer the questions of when and what. When did they buy the car? They bought the car in May. What is on the shelf? The books are on the shelf. What time will the meeting start? The meeting will start at midnight.

Now, the list of questions these two-letter words can answer goes on and on. So, if you want to master the art of using prepositions, check out this basic tutorial for additional tips and tricks.
