📚 Chapter Study Notes: Prepositions (Grammar - CEFR A2 Level)

Hello future English experts! Welcome to the chapter on Prepositions. Think of prepositions as the small but mighty words that act like the GPS system of your sentences. They tell us where, when, and how things are related.
Mastering them is key to sounding natural, clear, and confident in your English!

1. What Exactly Is a Preposition?

Definition and Role

A preposition is a short word (like on, at, with, under) that connects a noun or pronoun (the object of the preposition) to another word in the sentence.

Their main job is to show the relationship between things, usually concerning time, place, or direction.

Example: The cat jumped over the fence.

  • Preposition: over
  • Object of the Preposition: the fence
  • Relationship Shown: Movement/Position

🔑 Quick Takeaway: Prepositions are the essential "glue" words that show relationship and location.

2. Prepositions of PLACE (Location)

These tell us where something is. The three most common (and sometimes confusing!) are IN, ON, and AT.

A. IN (Used for large areas, enclosed spaces, or containers)

Think of IN as meaning "inside."

  • Large Geographical Areas: Countries, cities, neighbourhoods.
    Example: I live in London.
  • Enclosed Spaces/Rooms: Buildings, rooms, boxes.
    Example: The keys are in the box.
  • Vehicles you can walk inside of: Cars, trains, planes.
    Example: She is in the taxi.
B. ON (Used for surfaces, lines, and specific floors)

Think of ON as meaning "touching the surface of."

  • Surfaces: Tables, walls, floors.
    Example: The picture is on the wall.
  • Specific Floors:
    Example: My office is on the third floor.
  • Lines/Paths: Rivers, roads, coasts.
    Example: We live on the main street.
C. AT (Used for specific points or general locations)

Think of AT as meaning "a specific spot" or "attending a location."

  • Specific Addresses/Points:
    Example: Meet me at the corner. (Specific point)
  • Activities/Institutions: Showing that you are generally at that place for its purpose.
    Example: She is at school. / We are at the cinema.

🧠 Memory Aid for IN, ON, AT (Place): The Target Analogy

Imagine a target:

  • IN: The entire region/country (the biggest circle).
  • ON: A street or surface (a smaller circle).
  • AT: The specific dot/address (the bullseye).
D. Other Key Place Prepositions (Spatial Relations)
  • under: Below something. (The ball is under the chair.)
  • next to / beside: Right beside something. (The shop is next to the bank.)
  • between: In the space separating two things. (The park is between the library and the post office.)
  • in front of: Directly ahead of something. (The teacher stands in front of the whiteboard.)
  • behind: At the back of something. (The car is parked behind the house.)

3. Prepositions of TIME

These tell us when something happens. We use IN, ON, and AT again, but the rules change for time periods!

A. AT (Used for specific clock times and specific holidays)

Use AT for the most precise time.

  • Clock Times:
    Example: The film starts at 8:00 p.m.
  • Specific Moments: at noon, at midnight, at sunrise, at Christmas (the day itself)
B. ON (Used for specific days and dates)

Use ON when you name the day or the full date.

  • Days of the Week:
    Example: I have class on Monday.
  • Specific Dates:
    Example: Her birthday is on May 15th.
C. IN (Used for longer periods of time)

Use IN for everything else that lasts a long time.

  • Months: in July, in December
  • Years: in 2024, in 1999
  • Seasons: in the summer, in the winter
  • Parts of the Day (except 'at night'): in the morning, in the afternoon

🔑 Quick Review: The Length Rule (Time)

  • AT: The shortest time (precise time).
  • ON: Medium time (a day).
  • IN: The longest time (month, year, season).
D. Time Duration and Sequence

These prepositions help explain how long something lasts or when events happen.

1. During, Before, After

  • during: Throughout a period of time.
    Example: I slept during the flight.
  • before: Earlier than a specific time/event.
    Example: Eat breakfast before school.
  • after: Later than a specific time/event.
    Example: I will clean up after the party.

2. FOR vs. SINCE (A Common Mistake!)

Don't worry if this seems tricky at first—this confusion happens to everyone! Here is the simple way to remember it:

  • FOR: Tells you the duration (how long). It answers the question, "How many minutes/hours/years?"
    Example: I have lived here for ten years. (Duration = 10 years)
  • SINCE: Tells you the starting point (when it began). It needs a specific moment in the past.
    Example: I have lived here since 2014. (Starting point = 2014)

4. Prepositions of Movement and Direction

These prepositions show movement from one place to another.

  • to: Shows movement towards a destination. (The most common direction preposition.)
    Example: We walk to the library every day.
  • from: Shows the origin or starting point.
    Example: The train arrived from Paris.
  • into: Shows movement entering an enclosed space.
    Example: He walked into the room.
  • out of: Shows movement exiting an enclosed space.
    Example: She took the books out of her bag.
  • through: Shows movement from one side of an opening/area to the other.
    Example: We drove through the tunnel.

💡 Did You Know? Be careful with to! When to comes before a verb (to eat, to run), it is part of an infinitive, not a preposition!

5. Common Usage and Pitfalls

While the focus at A2 is mainly on time and place, you will also frequently see prepositions used to express other simple relationships.

A. Prepositional Usage (A2 Basics)
  • with: Showing accompaniment, possession, or instrument.
    Example (Accompaniment): I went to the park with my friend.
    Example (Instrument): Cut the paper with scissors.
  • of: Showing possession, belonging, or part of a whole.
    Example: The cover of the book is blue. (Possession/relationship)
  • about: Showing the topic or subject.
    Example: We talked about the homework.
B. Important Rules and Mistakes to Avoid

Mistake 1: Forgetting the Noun/Object
Prepositions must always be followed by a noun or pronoun. They never stand alone.
Incorrect: I arrived at.
Correct: I arrived at the station.

Mistake 2: Confusing Place and Time `AT`
Remember the difference:

  • Place: Use at for a specific address or point. (at the park)
  • Time: Use at for a specific clock time. (at 3:00 p.m.)

Mistake 3: The `On` Vehicle Rule
If you stand or move on the vehicle (like a bus or train), use on. If you sit in it (like a small car or taxi), use in.
I am on the bus, but I am in the car.

C. Final Encouragement

Prepositions are about practice and listening. The more you read and hear native English, the more the correct usage will feel natural. Don't worry about memorizing every single rule perfectly; focus on getting the "Big Three" (IN, ON, AT) right first!

Keep up the great work!
