Is it in or on? Is it for or from? Is it by or with? English prepositions can be so confusing. Even my most advanced students often tell me that prepositions are their biggest struggle. As many of you know, I teach the American accent to professionals who are quite fluent in English, and they use English every day at work, but they still struggle with using the correct preposition.
Prepositions don't always follow clear rules, and they don't often translate directly from your native language. And some prepositions don't make any sense. For example, why do we say Christmas is in December, but Christmas is on December 25th? Why do we say in Los Angeles, but at the post office?
I will teach you some of the most common mistakes. I will start with some easier rules, and then later in the video, the rules and the patterns will get more advanced. And I will give you a chance to test yourself as we go. Okay, let's get started.
Part 1: Place Prepositions ("In" vs. "At")
Let's start with an easy one. Let's look at in versus at when we're talking about places. Why do we say in New York, but at the airport?
We use in for larger areas. For example, I live in Los Angeles. She works in New York. We also use in for enclosed spaces. They are in the room. They're inside the room. He's in the building.
And we use at for specific locations, especially when we think of being at a place for an activity or for a purpose. For example, I'm at the market. I'm there to do the shopping. He's at the bus stop. They're at the restaurant.
Let's compare these two examples. What is the difference in meaning?
Let's meet at the restaurant.
Let's meet in the restaurant.
If I say at the restaurant, I mean at that location. We're going there to eat. That's an activity. However, I'm not specifying if we're going to meet in front of the restaurant or in the parking lot or inside the restaurant. But, if I say, let's meet in the restaurant, that means inside the restaurant, not outside, inside the physical building.
Here's another example. I saw her when I was at the market. I was there shopping. I can't talk right now. I'm in the market, but I will call you back as soon as I get out. You see the difference?
Part 2: Addresses ("On" vs. "At")
Let's look at another confusing prepositions pattern. Let's look at on and at with addresses.
When we mention just the name of the street, we say on. She lives on Main Street. My office is on Washington Boulevard. But, when we add the number of the street, we use at. She lives at 537 Main Street. The office is at 1356 Washington Boulevard. So, on if you just say the name of the street, and at if you give the full address with the number.
I remember there used to be a billboard, an advertisement for a car dealership in Los Angeles. It said, "in Santa Monica, on Santa Monica." Do you understand that? Native speakers do. It means that it's in the city of Santa Monica. For cities, we use the preposition in, and native speakers understand that on means on Santa Monica Boulevard. So, the advertisement was saying that you can find this car dealership in the city of Santa Monica on Santa Monica Boulevard.
But, remember, with very specific locations, we use at. At the intersection of, at the corner of. Let's meet at the corner of Broadway and Wall Street.
Part 3: Dates ("In" vs. "On")
Let's look at another confusing prepositions rule. Let's look at dates.
If we only say the month, we say in. In July, in August, in September. But, when we add a specific day of the month, we say on. On July 4th, on August 22nd, and so on. So, we would say, her birthday is in April. Her birthday is on April 10th.
Part 4: Adjectives Followed by Prepositions
Okay, and now it's going to get a little more advanced. Let's look at some adjectives followed by prepositions. And these are some very common mistakes.
Good / Bad / Terrible + At
Let's look at the adjectives good and bad. What do we say in this case?
I'm good math. He's good tennis.
Which preposition do we use? We use at. I'm good at math. He's good at tennis.
And let's look at bad. It follows the same pattern. Bad at. I'm bad at remembering names, but I'm good at recognizing faces. He's bad at understanding fast speech, but he's good at reading English.
And terrible follows the same pattern. Terrible at. I'm terrible at remembering names.
Known + For
Let's look at some more adjectives that follow prepositions. Let's look at known. We can say, he's well known. He's known his scientific research. Do you know the correct preposition? You say it.
Did you say known for? If you did, good job. That's a hard one. Known for means famous for something, recognized for a skill or for a characteristic. We can say, she's known for her beautiful voice. This restaurant is known for its pasta. Who is he, and what is he known for?
Married / Engaged + To
Here's another common mistake with the preposition followed by an adjective. Married. She's married John. What's the correct answer? You say it.
Did you say to? Yes, that's correct. She's married to John, not she's marriedwithJohn.
And engaged is the same when two people agree to get married. Engaged to. He's engaged to Emily. She got engaged to her high school sweetheart. Married to, engaged to. Notwith.
Disappointed + In / With
Let's go on to the next one. Let's look at disappointed. This one has two possible answers depending on the meaning.
I'm disappointed you.
I'm disappointed the film.
Different preposition is required. If I say I'm disappointed you, which preposition should I use? In. I'm disappointed in you. I'm disappointed in you for lying to me. Disappointed in when it's a person. I'm disappointed in myself for failing the exam.
But, look at this example. I'm disappointed the movie. A movie is a thing, not a person. So, what would we say in that case? Which preposition would we use? I'm disappointed with. I'm disappointed with the movie. When we're talking about things or situations or results, we would use with. I was disappointed with the hotel. They are disappointed with the quality of the product. So, remember, disappointed in a person, disappointed with a thing.
Absent + From
Let's look at another adjective, absent. He was absent work yesterday. What is the correct preposition? You say it.
Absent from. He was absent from work yesterday. He's been absent from class 3 days this month.
Dressed + In
Let's go on to the next one. This one is also confusing. Dressed. Why are you dressed black? You're wearing all black. What do we say? Dressed.
Dressed in. He's dressed in black. He's dressed in an elegant suit. Dressed in.
Composed + Of
Let's go on to the next one. Actually, this one may not be that hard. I have a feeling many of you know this one. Composed. Water is composed hydrogen and oxygen. What do we say?
Composed of. The team is composed of strong players. Did you know that one? I have a feeling you did.
Part 5: Verbs with Prepositions ("Made")
Okay, now let's look at some verbs with prepositions. Let's look at the verb to make in the passive voice, made. It can have three possible prepositions with three meanings. We can say made of, made from, or made out of. They're slightly different.
We use made from when the original material is changed or transformed, and you can't clearly see it anymore. For example, paper is made from wood. Wine is made from grapes. We would not say wine is made of grapes or out of grapes. Cheese is made from milk.
Let's look at made of. We use made of when the original material is still visible or it's recognizable in the final product. For example, the table is made of wood.
Let's compare these two sentences:
Paper is made from wood.
The table is made of wood.
You see the difference? Wine is made from grapes. We can't see the grapes anymore, but the ring is made of gold. We still see the gold. Cheese is made from milk. The house is made of bricks.
