Welcome to the World of Prepositions!

Hi there! Today, we are going to explore Prepositions. Think of prepositions as the "glue" or the "bridge" in a sentence. They help us connect people, objects, time, and locations so that our sentences make sense. Without them, we wouldn't know when a party starts or where we left our schoolbags!

Don't worry if this seems a bit confusing at first. Even native speakers sometimes mix them up! By the end of these notes, you’ll have some great tricks to remember which word to use and when.

1. Prepositions of Time (When?)

The most common prepositions of time are in, on, and at. A great way to remember them is to think of a Pyramid. We move from the "General/Big" (top) to the "Specific/Small" (bottom).

IN (General - Big periods of time)

Use in for long periods like months, years, seasons, or parts of the day.

  • Months: in July, in December
  • Years: in 2024, in the 21st century
  • Seasons: in summer, in winter
  • Parts of the day: in the morning, in the afternoon, in the evening

ON (More Specific - Days and Dates)

Use on when you can point to a specific square on a calendar.

  • Days of the week: on Monday, on Friday
  • Specific dates: on 1st October, on my birthday
  • Special days: on Christmas Day, on School Anniversary Day

AT (Very Specific - Precise Times)

Use at for exact clock times or specific moments.

  • Clock times: at 7:30 a.m., at 4 o'clock
  • Meal times: at lunchtime, at dinner
  • Precise moments: at night, at the moment, at the weekend

Quick Review Tip: Remember this rhyme: "In the month, On the day, At the clock time – that's the way!"

Key Takeaway:

In = Big/Long periods. On = Days/Dates. At = Exact times.

2. Prepositions of Place (Where?)

Just like time, we use in, on, and at to describe where things are.

IN (Inside an enclosed space)

Use in when something is inside a container, a room, or a large geographical area.

  • in a box, in the classroom, in Hong Kong, in the park

ON (On a surface)

Use on when something is touching the top of a surface.

  • on the table, on the floor, on the wall, on the blackboard

AT (A specific point or location)

Use at when you are talking about a specific spot, but not necessarily "inside" or "on" it.

  • at the bus stop, at the door, at the entrance, at the top of the page

Did you know? We say on the bus or on the train because we can walk around on them, but we say in a car because we have to sit down right away!

Key Takeaway:

In is for inside. On is for surfaces. At is for a specific point.

3. Describing Positions (Where is it exactly?)

Sometimes in/on/at aren't enough. We need to be more descriptive!

  • Under / Below: When something is lower than something else. (Example: The cat is hiding under the chair.)
  • Over / Above: When something is higher than something else. (Example: The plane flew over the mountains.)
  • Next to / Beside: When something is very close to the side of another thing. (Example: Tim sits next to me in class.)
  • Between: When something is in the middle of two things. (Example: The shop is between the bank and the bakery.)
  • Opposite: When something is facing something else (usually across a street or table). (Example: The cinema is opposite the library.)

Common Mistake to Avoid: Don't confuse between and among. Use between for two things. Use among when there are three or more things (Example: The teacher is standing among the students.)

4. Prepositions of Direction and Movement

These words show that someone or something is moving from one place to another.

1. To: Shows the destination. (Example: I am going to school.)
2. Into: Moving from the outside to the inside. (Example: The frog jumped into the pond.)
3. Out of: Moving from the inside to the outside. (Example: Please take your books out of your bag.)
4. Across: Moving from one side to the other. (Example: Walk across the bridge.)
5. Through: Moving inside something from one end to the other. (Example: The train goes through the tunnel.)

Quick Review Box:

To = Destination
Into = Entering
Through = In and then out

5. Common Phrases with Prepositions

In English, some words just "stick" to certain prepositions. It’s a good idea to learn these as a pair!

  • Good at: I am good at English. (Not "good in"!)
  • Interested in: She is interested in music.
  • Afraid of: Are you afraid of spiders?
  • Famous for: Hong Kong is famous for its food.
  • Listen to: We should listen to the teacher.

Final Summary Checklist

Before your test, ask yourself these questions:

  • Am I talking about a day? Use ON.
  • Am I talking about a month or a year? Use IN.
  • Am I talking about a specific time? Use AT.
  • Is something moving inside? Use INTO.
  • Is something moving across a surface? Use ACROSS.

Keep practicing! Prepositions might feel like a lot of rules, but the more you read and speak, the more natural they will feel. You've got this!
