Part of Speech: What Kind of Word Is a Preposition?
A preposition is a part of speech. That means it is one kind of word in English grammar.
It is not a noun, verb, adjective, or adverb. It has its own job.
Its job is to show a relationship.
A preposition is usually followed by:
• a noun: in April
• a pronoun: with her
• a noun phrase: under the kitchen table
The noun or pronoun after the preposition is called the object of the preposition.
How Prepositions Work in a Sentence
A preposition usually begins a prepositional phrase. This phrase includes the preposition and its object.
Example:
The dog slept under the desk.
Here, under is the preposition. The desk is its object. The full phrase is under the desk.
Prepositional phrases can describe where, when, or how something happens.
More examples:
• We arrived before dinner.
• The picture hangs above the couch.
• He paid with a card.
• She moved from Texas.
Common Types of Prepositions
Prepositions can show different kinds of relationships. The most common types are time, place, and direction.
| Type | What It Shows | Examples |
|---|---|---|
| Time | when something happens | at 6, on Friday, in June |
| Place | where something is | in a box, on the wall |
| Direction | where something moves | to school, into the room |
Some prepositions show cause, manner, or purpose.
Examples:
• She left because of the storm.
• He wrote with a pen.
• This gift is for you.

• above
• after
• at
• before
• behind
• between
• by
• for
• from
• in
• into

How to Use Prepositions Correctly
Use a preposition when you need to connect a noun or pronoun to another idea.
Choose the preposition that matches the meaning. A small change can change the whole sentence.
Examples:
• She is in the car.
• She is on the bus.
• She walked to the store.
• She walked into the store.
Some prepositions are part of fixed phrases. These must be learned as full chunks.
Examples:
• interested in music
• good at math
• responsible for the report
• depend on your answer
A good habit is to learn the whole phrase, not just the single word.
Common Mistakes With Prepositions

One common mistake is choosing the wrong preposition.
Incorrect: I am good in math.
Correct: I am good at math.
Another mistake is adding a preposition where none is needed.
Incorrect: We discussed about the plan.
Correct: We discussed the plan.
Many people also worry about ending a sentence with a preposition. In modern English, it is often fine.
Natural: Who are you talking to?
Stiff: To whom are you talking?
The formal version is correct, but it may sound too stiff in everyday speech.
