1. Lesson Overview
In this lesson, you will learn:
- What prepositions are
- How prepositions show relationships
- Basic types: time, place, movement
- Prepositional phrases
- Object of a preposition
- Common beginner errors
Prepositions connect nouns to other words.
They show relationships in space, time, and logic.
2. Core Explanation
A. What Is a Preposition?
A preposition shows the relationship between a noun (or pronoun) and another word in a sentence.
Example:
Penguins live in Antarctica.
“in” connects “Antarctica” to the verb “live.”
B. Preposition + Object
A preposition is always followed by a noun or pronoun.
This combination is called a prepositional phrase.
Example:
The spacecraft landed on Mars.
on Mars = prepositional phrase
Mars = object of preposition
C. Prepositions of Place
Common examples: in, on, at, under, above, between, behind
The Great Pyramid is in Egypt.
The satellite is above the Earth.
The statue stands between two buildings.
D. Prepositions of Time
Common examples: in, on, at, during, before, after
Use rules:
- in → months, years, long periods (in 2020, in winter)
- on → days, dates (on Monday, on July 4)
- at → exact time (at 6 PM)
Example:
The conference begins at 9 AM on Monday in April.
E. Prepositions of Movement
Common examples: to, into, onto, across, through
The explorers travelled across the desert.
The astronaut moved into the spacecraft.
F. Prepositional Phrases
Preposition + object + modifiers
The research was conducted in the Arctic region.
The data were collected during the experiment.
Prepositional phrases often function as adjectives or adverbs.

5. Common Mistakes Spotlight
⚠ Incorrect time prepositions
Incorrect: at Monday

⚠ Missing object
Incorrect: She walked into.

⚠ Confusing in/on/at for place
Use “in” for large areas, “at” for specific points.
