English uses small words called prepositions to tell us where things are. For example, in, on, e under are common prepositions of place. We use in when something is inside a space or container, like The book is in the bag. This means the book is *inside* the bag. We use on when something is on a surface, like The apple is on the table. This means the apple is *touching the top* of the table. And we use under when something is below another thing, like The cat is under the chair. This means the cat is *below* the chair, not touching it. These words are very important for describing locations in English. Learning them helps you speak and understand simple sentences about where objects and people are. Practice with examples to remember them easily and improve your basic English communication.

Errori comuni per chi parla spagnolo

Spanish speakers often use 'en' for both in e on. In English, these words are different and important.

  • Corretto: The pen is on the book.
  • Errato: The water is on the bottle. (If it's inside the bottle)
  • Corretto: The water is in the bottle.

Remember to think: Is it *inside* a container or *on* a surface?
