Introduction

The book is the table.

What Is a Preposition?

A preposition is a word that shows the relationship between a Noun (or Pronoun) and another word in the sentence.

Prepositions often describe:

• Direction
• Time
• Movement
• Method

Examples of Prepositions

• The meeting starts at 10 am.

In these sentences, the prepositions connect ideas and provide important details.

Why Are Prepositions Important?

Prepositions make English:

Without preposition:

She is sitting the chair.

With preposition:

She is sitting on the chair.

The second sentence is correct and clear.

Prepositions may be small words, but they carry huge meaning.

A preposition often works with a noun to form a phrase.

Examples

• In the morning
• At school
• On the table
• Under the chair

These phrases are extremely common in English.

2. Read English Every Day
