C.1.7: Prepositions
A preposition is a word that connects a noun or a pronoun to another word in a sentence. Most prepositions such as above, below, and behind usually indicate a location in the physical world, but some prepositions such as during, after, and until show location in time.
In, At, and On
The prepositions in, at, and on are used to indicate both location and time, but they are used in specific ways. Study Table C.1.7.1, Table C.1.7.2, and Table C.1.7.3 to learn when to use each one.
Exercise 1
Edit the following letter from a resident to her landlord by correcting errors with in, at, and on.
Dear Mrs. Salazar,
I am writing this letter to inform you that I will be vacating apartment 2A in 356 Maple Street at Wednesday, June 30, 2010. I will be cleaning the apartment at the Monday before I leave. I will return the keys to you on 5 p.m., sharp, at June 30. If you have any questions or specific instructions for me, please contact me in my office. I have enjoyed living at Austin, Texas, but I want to explore other parts of the country now.
Sincerely,
Milani Davis
Prepositions after Verbs
Prepositions often follow verbs to create expressions with distinct meanings. These expressions are sometimes called prepositional verbs. It is important to remember that these expressions cannot be separated.
Tip
It is a good idea to memorize these combinations of verbs plus prepositions. Write them down in a notebook along with the definition and practice using them when you speak.
Exercise 2
On a separate sheet of paper, complete the following sentences by writing the correct preposition after the verb.
- Charlotte does not ________ (apologize for, believe in) aliens or ghosts.
- It is impolite to ________ (hear about, talk about) people when they are not here.
- Herman said he was going to ________ (believe in, apply for) the internship.
- Jonas would not ________ (talk about, apologize for) eating the last piece of cake.
- I ________ (care about, agree with) the environment very much.
Prepositions after Adjectives
Similar to prepositions after verbs, prepositions after adjectives create expressions with distinct meanings unique to English. Remember, like prepositional verbs, these expressions also cannot be separated.
Exercise 3
On a separate sheet of paper, complete the following sentences by writing the correct preposition after the verb.
- Meera was deeply ________ (interested in, thankful for) marine biology.
- I was ________ (jealous of, disappointed in) the season finale of my favorite show.
- Jordan won the race, and I am ________ (happy for, interested in) him.
- The lawyer was ________ (thankful for, confused about) the details of the case.
- Chloe was ________ (dressed in, tired of) a comfortable blue tunic.
