When I first started teaching prepositions, I made a mistake. I taught them as three separate topics — time prepositions, place prepositions, movement prepositions — as if they were completely different creatures. But after a few years, I realized my students learned faster when I showed them the connections. Prepositions of movement, for example, are often just place prepositions “in action.” Once you see the pattern, everything becomes manageable.
You’ll learn which preposition pairs go with which situations, and why the same word sometimes works in very different contexts.
Key Takeaways
- Prepositions of time answer “when?” — at (exact time), in (period), on (day), by (deadline), since (start point), for (duration), during (throughout).
- Prepositions of place answer “where?” — in (inside), on (surface), under (below), above (over), beside/next to (adjacent), between (in the middle), behind, in front of.
- Prepositions of movement answer “in which direction?” — to (destination), into (inside), out of (exit), through (across), across (side to side), along (following a path).
- Same prepositions, different meanings: “In” can mean time (in May), place (in a room), or movement (go in the car). Context determines meaning.
- Learn one rule, master three: Many prepositions work across all three categories once you understand the core meaning.
What Are Prepositions? A Quick Review
A preposition is a word or phrase that shows the relationship between a noun (or pronoun) and other parts of a sentence. Prepositions come before the noun they relate to — that’s why they’re called “prepositions” (pre- = before).
Example: “The cat is under the table.” The preposition “under” shows the relationship between the cat and the table.
Prepositions have three main categories based on what they describe: time (when something happens), place (where something is), and movement (how something gets from one place to another).
Prepositions of Time — When Does It Happen?
Prepositions of time tell us when an action occurs or when something exists. They answer the question: “When?”
Key Time Prepositions
| Preposition | Use | Example |
|---|---|---|
| AT | Exact clock time; specific moment (mealtimes, holidays without “day”) | at 3 o’clock, at breakfast, at Easter |
| IN | Months, years, seasons, time periods, parts of the day | in May, in 2020, in the morning |
| ON | Days of the week, dates, special days with “day” | on Monday, on April 5th, on Valentine’s Day |
| BY | Deadline; latest time something must be done | by Friday, by 5 PM (must finish before or at this time) |
| BEFORE | Earlier than a point in time | before noon, before the meeting starts |
| AFTER | Later than a point in time | after lunch, after I finish studying |
| SINCE | Starting point; action that began then and continues | since Monday (action started Monday, continues now) |
| FOR | Duration; how long something lasts | for 3 hours, for two weeks, for a long time |
| DURING | Throughout a period; within a time span | during the movie, during winter |
| UNTIL / TILL | Up to a point; up to a deadline | until Friday, until midnight |
Examples in Full Sentences
Example 1: I have a dentist appointment at 2 PM.
Example 2: Most people are busy during the holiday season.
Example 3: I’ve been learning English since January.
Example 4: Please finish your homework by tomorrow.
Example 5: She studied for three hours before the exam.
Since vs. For: “Since” marks the start point (since Monday = starting from Monday). “For” marks the duration (for two weeks = a length of time). Use: “I’ve lived here since 2010” (start). “I’ve lived here for 15 years” (length).
Prepositions of Place — Where Is It?
Prepositions of place tell us where someone or something is located. They answer the question: “Where?”
Key Place Prepositions
| Preposition | Use | Example |
|---|---|---|
| AT | Specific point or location (shops, events, addresses) | at the bank, at the party, at 42 Main Street |
| IN | Inside a larger area or enclosed space (cities, rooms, containers) | in the room, in Canada, in the box |
| ON | On a surface; on a street or road | on the table, on the wall, on Main Street |
| UNDER | Directly below; beneath something | under the bridge, under the bed |
| ABOVE | Higher than; over something | above the clouds, above the entrance |
| BELOW | Lower than; beneath something | below the surface, below sea level |
| BESIDE / NEXT TO | Right next to; immediately adjacent | beside the river, next to the door |
| BETWEEN | In the middle of two things | between the buildings, between you and me |
| BEHIND | At the back of something | behind the curtain, behind the house |
| IN FRONT OF | Facing something; ahead of something | in front of the museum, in front of the TV |
| NEAR | Close to but not immediately adjacent | near the park, near the beach |

Example 1: I left my keys on the kitchen counter.
Example 2: There’s a gas station near our house.
Example 3: The sculpture is between the two buildings.
Example 4: She hid behind the door to surprise him.

| □ On the table | ON | Resting on top of a surface |
| ⚪ In the box | IN | Inside a container or enclosed space |
| 🔻 Under the table | UNDER | Directly below something |
| ◄ ► Behind / In front | BEHIND / IN FRONT OF | At the back or front side |
Prepositions of Movement — Which Direction?
Prepositions of movement describe motion or direction. They’re often used with action verbs (go, walk, run, move, jump). They answer the question: “In which direction?” or “How does it get from A to B?”
Key Movement Prepositions
| Preposition | Use | Example |
|---|---|---|
| TO | Direction toward a destination | go to school, travel to Japan |
| TOWARD | Moving in the direction of (may not reach destination) | walking toward the park, heading toward home |
| FROM | Starting point of movement | come from the store, travel from London |
| INTO | Movement inside; entering a space or condition | go into the room, dive into the pool |
| OUT OF | Movement exiting a space | get out of the car, run out of the house |
| THROUGH | Movement from one side to the other, passing within | walk through the park, go through the tunnel |
| ACROSS | Movement from one side to the opposite side | run across the street, swim across the river |
| OVER | Movement above and then down the other side | jump over the fence, fly over the mountain |
| UNDER | Movement below something | crawl under the fence, go under the bridge |
| ALONG | Movement following a path or edge | walk along the beach, run along the river |
| AROUND | Movement in a circular path; motion on all sides | drive around the city, run around the field |
| UP / DOWN | Vertical movement: upward or downward | climb up the ladder, walk down the stairs |
Examples in Full Sentences
Example 1: He walked toward the exit but didn’t leave.
Example 2: We drove across the country last summer.
Example 3: She swam through the lake to reach the island.
Example 4: The hikers climbed up the mountain all morning.
Example 5: I’m taking you to the airport now.
Common Mistakes Learners Make
✗ Incorrect: I’ll wait for you until you come back.
✓ Correct: I’ll wait for you until you come back.
Why: “Until” marks the endpoint (when the waiting stops). “For” marks the duration (how long you’ll wait). Use both together or choose one depending on context.
✗ Incorrect: I go in the store for milk.
✓ Correct: I go to the store for milk.
Why: Use “to” for direction/destination. “In the store” describes location when you’re already there, not the movement toward it.
✗ Incorrect: I’ve been living here for since 2010.
✓ Correct: I’ve been living here since 2010.
Why: Don’t use both “for” and “since” together. Choose one based on whether you’re stating a starting point (since) or a duration (for).

Sample Dialogue
Tourist: Excuse me, can you tell me how to get to the museum?
Local: Sure! Walk straight ahead for two blocks, then turn left. The museum is between the library and the post office.
Tourist: How long does it take to get there from here?
Local: About 10 minutes. Go through the park and you’ll see it on the right side of the street.
Tourist: Thank you! I’ll go there after lunch, around 1 PM.
Local: Perfect! Just be aware that on weekends it gets very crowded.
Prepositions Across All Three Categories
Some prepositions work in all three categories. The meaning changes based on context:
| Preposition | Time Use | Place Use | Movement Use |
|---|---|---|---|
| IN | in May (period) | in the room (inside) | go in the car (inside for transport) |
| ON | on Monday (day) | on the table (surface) | ride on a bike (surface/top of) |
| AT | at 3 PM (time) | at the station (location) | aim at the target (direction) |
| UNDER | under 30 years old (condition) | under the bridge (below) | crawl under the fence (beneath) |
| AROUND | around noon (approximately) | around the house (perimeter) | drive around the block (circular) |
Once you understand the core meaning of each preposition, you can apply it across contexts.

Frequently Asked Questions
What’s the easiest way to remember all these prepositions?
Group them by the question they answer: “When?” (time), “Where?” (place), “In which direction?” (movement). This framework works for any preposition. When you see an unfamiliar preposition, ask yourself one of these three questions to figure out its category.
Why do “in,” “on,” and “at” appear in all three categories?
These three prepositions are the most common and flexible. Once you understand their core meanings (in = inside/enclosed, on = surface, at = point), you can apply them across time, place, and movement contexts.
Is “into” different from “in”?
Yes. “In” describes a static position (you are in the room). “Into” describes movement (you go into the room). The same applies with “out of” versus “out.” Always use “into” and “out of” when describing direction or motion.
Can I use “to” and “toward” interchangeably?
“To” means you reach the destination: “I’m going to the store.” “Toward” means moving in that direction but not necessarily reaching it: “I walked toward the exit.” If you’re sure about the endpoint, use “to.” If it’s just a direction, use “toward.”
When should I use “by” versus “until”?
“By” is a deadline (you must finish by Friday = no later than Friday). “Until” is an endpoint (I’ll stay until noon = stopping at noon). “By” emphasizes that something needs to be done; “until” emphasizes how long something continues.
What’s the rule for “since” and “for”?
“Since” requires a starting point (since 2010, since Monday, since I was born). “For” requires a duration (for 10 years, for two weeks). Remember: “Since” + specific point in time; “For” + length of time.
