For being such tiny little words, prepositions cause very big problems. Even native speakers make preposition mistakes, which makes mastering these words and their usage harder for English learners. On this page, we will talk about the right way to use prepositions and, more importantly, why each preposition is used that way. Here, you can get an idea of the lesson ahead.
| ❌ Mistake | ✅ How to fix it | ❓Why |
|---|---|---|
| He walked in the room. | He walked into the room. | 'Into' shows movement. 'In' shows position. |
| I received the book of my friend. | I received the book from my friend. | 'From' indicates origin. 'Of' means 'what the book is about'. |
| She shared the food between her family. | She shared the food among her family. | 'Among' means 'three or more people'. 'Between' is for two people only! |
| I'm in the bus. | I'm on the bus. | Large transportation - buses, planes, trains, etc. - require 'on'. Smaller transport, such as a car, need in. "Get in the car!". |
| I'm meeting him at Wednesday. I'm meeting him in Wednesday. | I'm meeting him on Wednesday. | 'At' and 'in' are for location and time. Days of the week always use 'On'. |
| My father always gets home in night. | My father always gets home at night. | Use 'in' for morning, afternoon, and evening. Use 'at' for night. |
| She arrived to school two hours late. | She arrived at school two hours late. | 'At' means reaching at destination. 'To' means travelling to the destination. |
| We will meet after an hour. | We will meet in an hour. | 'In' is a specific window of time. 'After' suggests the meeting could take place anytime, maybe even 3 hours later! |
| I have worked here since 5 years. | I have worked here for 5 years. | 'Since' describes a starting point. 'For' describes a span of time. |
| I will stay to 8 o'clock. | I will stay until 8 o'clock. | 'Until' describes how long something will happen. 'To' is used for a window of time: "10 AM to 3 PM", for example. |
Preposition Mistakes Using 'At'
This preposition has to be the most confusing of all. English speakers use 'at' to describe time, location, and direction. 'At' has many other uses besides those, such as, "What are you getting at?" and "Quit picking at your scab!". To make matters worse, 'at' usage varies from one English-speaking country to the next.
American English speakers say "... on the weekend."
British English speakers say "... at the weekend."
The best and easiest way1 to find a path through all this confusion is to first master prepositions of time, as well as other uses for 'at'. But learning them during your English lessons isn't enough. You must constantly practise using them until 'at' falls naturally into your English speaking.
'At' For Specific Times
'At' is the right preposition for when you talk about what time you wake up, what time you eat, and what time you will meet your friends.
The common mistake
- I wake up 6:30 every day.
- We always eat in noon.
- Let's meet on 8:00 in front of cinema.
- I went dancing at last Saturday.
Say it correctly
- I wake up at 6:30 every day.
- We always eat at noon.
- Let's meet at 8:00 in front of the cinema.
- I went dancing last Saturday.
Unlike English, several other languages do not use prepositions to define time or place. So, it's quite common for English learners to leave out 'at' if their own language does so. Using the preposition 'in' to define time is equally confusing - but only until you know the rule.
I wake up in the morning.
I eat in the late afternoon.
I always meet my friends in the evening.
But never I go to sleep in the night!
'At' For Locations
The preposition 'at' has many uses in English, particularly for locations. You can be at the dentist, at the movies, or at home. School is also a place you can be at, but you can also be in.
'At' can mean direction (I threw my pen at my classmate) but the usage above is incorrect. One walks to school because 'to' means movement - you are moving, while 'at' means standing still (your classmate was standing or sitting still).
Do not use 'at' for countries, cities, or regions.
Don't say: I live at Beijing. Do say: I live in Beijing.
Don't say: Hollywood is at California. Do Say Hollywood is in California.
It's as tricky to use prepositions of place correctly as it is to use time prepositions. Here, too, you only have one way to get good at it: practice, practice, and more practice.
Avoid 'At' Preposition Errors
- Use 'at' for specific times and places - "At my house"; "At 6:30"; "At the gym".
- Use 'at' for events and actions: "The concert at the mall"; "The accident at the train station".
- Use 'at' for fixed expressions: "at best"; "at all"; "at any time"; "at last!".
- Use 'at' to describe things you do: "I'm good at English"; "He's terrible at basketball".
Preposition Errors Using 'In'
Like 'at', the preposition 'in' has many uses2. We use 'in' for time, place - just like 'at', as well as how long something lasts and being in a particular state. You can also use 'in' as a preposition of manner to describe how things are done. With all these ways to use this preposition, making mistakes is almost expected.
Common mistakes using 'in'
- I'm in the bus.
- She walked in my room without asking.
- My mother always goes out at the morning.
- I was born 2004.
Say it correctly
- I'm on the bus.
- She walked into my room without asking.
- My mother always goes out in the morning.
- I was born in 2004.
If you and your classmates make mistakes such as these, don't be too hard on yourselves. The trouble could simply be that your English books don't lay out the rules for using 'in' clearly.
Mistakes Using 'In' and How to Fix Them
Location is probably the most frequent usage this preposition sees, but that comes with rules. For instance, when you talk about a place inside an enclosed area, you must use 'in'.
- I live in Singapore. Singapore has city limits; it is an enclosed area.
- I'm in my room! Your room is a smaller space, with walls, inside the larger home.
- My book is in my desk drawer. A drawer is a small, enclosed space.
- I prefer my beer in a glass. A glass is a container.
Common preposition mistakes in these instances include using 'from' instead of 'in' (I prefer my beer from a glass), my book is in my desk (a desk is not an enclosed space), and leaving out the preposition (I live Singapore).
Using 'In' to Describe Time
'In' sees lots of usage when talking about time-related matters. One way to use 'in' relates to general time, months, seasons, and years. These are common mistakes (and their corrections) for such instances.
- I'll clean the kitchen at the morning.
- I was born September.
- It always rains a lot during Autumn.
- My house was built 1995.
- I'll clean the kitchen in the morning.
- I was born in September.
- It always rains a lot in Autumn.
- My house was built in 1995.
You'll note that omission - leaving out the preposition - is the most common mistake. Using the wrong preposition is the second most frequent mistake.
We use 'during' to talk about things that happen throughout a certain time.
For example: "They ate popcorn during the movie."
It means that from the start to the finish of the movie, they were eating popcorn.
Monsoon-prone regions might see rain every day throughout the month but that's an unusual case. Besides, 'during' has its own rules for usage which do not include general time descriptions. So, 'in' wins this battle - because the rules say so!
Preposition Mistakes Using 'On'
I'm just waiting on a friend.
The Rolling Stones
You might have heard native speakers make preposition mistakes in films, song lyrics, and podcasts. This song is a good example of such a mistake.
Now that you've heard a native English band use prepositions incorrectly - one of the biggest bands in music history! - it's time to learn the rule for using 'on'. you must always use 'for' with 'wait', and 'to' with agree.
The common mistake
- I'm waiting on my test results.
- I'm waiting on my mother to get home.
- I'm waiting on a package delivery.
- We agreed on that much, at least.
- We agreed on a plan to ace our test.
The correct way
- I'm waiting for my test results.
- I'm waiting for my mother to get home.
- I'm waiting for a package delivery.
- We agreed to that much, at least.
- We agreed to a plan to ace our test.
The exception to the 'on-wait' rule is when you visit a restaurant or shop. There, workers wait on customers. They bring what their patrons ask for and collect money for the services they provide.
The preposition 'on' suffers from many other misuses. However, unlike the prepositions above, 'at' and 'in', 'on' typically gets overlooked; people use other prepositions, instead. Common mistakes include:
The mistakes
- The book is at (or in) the table.
- I am in the train.
- It depends about (or from) your schedule.
The correct way
- The book is on the table.
- I am on the train.
- It depends on your schedule.
The intent of a preposition is as a 'clarifier'. These words help speakers establish relations between words and groups of words, particularly when talking about time, place, and action.
These relations give spoken language context and meaning. English is not a very precise language so it needs special words, such as prepositions, to help make meanings clear.
Other Common Errors in Preposition Usage
Unfortunately, the preposition word group is hard to master. It has many rules, and just as many exceptions to those rules. Two factors make preposition usage even more challenging for English learners:
Translating from their native language.
Native English speakers using prepositions incorrectly.
And one more aspect makes these little words so devilish: the fact that they have specific uses3. For instance, it's easy to confuse prepositions of movement - into, onto, towards, and others - with location prepositions (in, on, and to). Indeed, even native speakers tend to use these interchangeably.
So, we leave you with a chart that describes categories of preposition mistakes, some examples and their fixes, as well as explanations for each.
| ❌Mistake | ✅Fixing it | ❓Why |
|---|---|---|
| Leaving out prepositions | ||
| We'll go out Saturday. I was born 1998. I go work now. | We'll go out on Saturday. I was born in 1998. I go to work every day. | Specific days of the week require 'on.' 'In' makes the connection between the verb and the date. 'To' indicates travel. |
| Using the wrong preposition | ||
| She put the food into my mouth. Put the book in the table. I'm off work at the afternoon. | She put the food in my mouth. Put the book on the table. I'm off work in the afternoon. | 'Into' indicates travel; the food isn't travelling! 'In' is for enclosed spaces. 'At' is for specific times, not general time frames. |
| Placing the preposition incorrectly. | ||
| Put back the book. I already showed you it. We looked them after (the children). We listened it already. | Put the book back. I already showed it to you. We looked after them (the children). We listened to it already. | When using phrasal verbs, the preposition can be split from verb. When using prepositional verbs, they cannot be split. |
| Using the wrong preposition with specific verbs | ||
| I rely with you to tell me the truth. She depends upon her parents for everything. I believe onto you. | I rely on you to tell me the truth. She depends on her parents for everything. I believe in you. | Some verbs require a specific preposition to make sense. |
| Translating from one's native language. | ||
| I am work off Saturday. I heard about the tsunami at school. | I am off work on Saturday. I heard about the tsunami while at school. | Weekdays require 'on'; note word order. The school did not have a tsunami, 'while' defines where you were at when you heard about the tsunami. |
