Preposition Checker

Prepositions may be short words or phrases but when used incorrectly, they could change the context of a sentence. So, it's important that you keep an eye on your prepositions. One way to do this is to use a preposition finder like INK's Preposition Checker tool.

Main Takeaways:

  • A preposition indicates the relationship between a noun or pronoun and other sentences.
  • There are five types of prepositionspreposition of time, place, movement, agents, and places.
  • There are specific rules for using prepositions in English grammar.
  • INK Preposition Checker can help you avoid errors and increase your writing efficiency.

What is a Preposition?

Prepositionsare usually short words that indicate the relationship between a noun or a pronoun and other terms in a sentence. In the English language, we use prepositions to link nouns, pronouns, or phrases within a sentence. Think of these words as the glue that holds sentences together, and they do this by expressing order, time, connections, and positions.


  • The water in the glass is hot.

The preposition "in" used in the sentence above shows the relationship between the water and the glass.

Prepositions are an essential part of our speech and writing. They account for the most frequently used words in all of English. These include terms such as of, to, for, with, at, and on, among others.

Ideally, you'll find a preposition in front of nouns. But, you can also place them in front of gerund verbs.


  • I am going to Detroit.
  • She gave a book to him.
  • He devotes his time to reading.

Unlike nouns and verbs, it's impossible to add new words to prepositions over time. That's why we refer to them as a "closed class of words" in English.

Also, prepositions do not have any other form. That means they can't be plural, inflection, or possessive.

What's more, most prepositions have various contextual and natural uses, which makes them more confusing. Sometimes, these words can function as nouns, adverbs, and adjectives.

A preposition finder can help you avoid these confusions. But before we explore the benefit of INK Preposition Checker, let's discuss the types of prepositions first.

What are the Types of Prepositions and Examples

1. Prepositions of Time

As you may have guessed, prepositions of time indicate when something happened, happens, or will happen. Some examples of this type of preposition include: at, in, on, after, and before.

Since many prepositions fit into this category, it can get a little confusing.


  • Charlie was born on July 4th, 1776.
  • She was born in 1776.
  • Jane was born at 5 am.
  • She was born five minutes after her twin brother.
  • She was born before the Great War began.

In the sentence above, five different prepositions indicate when something happened. This may seem confusing at first glance, but a set of guidelines can help decide which to use.

Consider using the preposition "in" if you're dealing with months, seasons, centuries. On the other hand, days, dates, and specific holiday days would require the preposition "on."


  • I met Logan in 1995
  • It's hot in September.
  • The new year is on January 1st
  • She gave her a present on her birthday.

The prepositions "before" and "after" indicate when something happened, will happen, or occur in relation to another thing.

  • He left before 10 am.
  • Clark comes before Diana in the line but after Bruce.

Other prepositionsof time include about, around, during, until, and throughout.

2. Preposition of Place

In English, we use prepositions of place to indicate position. To make things a bit more confusing, the most common prepositions of timeat, in, on— are the most common preposition of place.

But, identifying place prepositions is not as complicated as the time counterpart.

Here's a breakdown of the guidelines.

​1. Use the preposition "on" to refer to something with a surface.


  • The painting hangs on the wall.

​2. Use the word "In" to refer to something that's inside or within confined boundaries.


  • Charles is in Paris
  • He spends his free time running in the park.

​3. Use the preposition "at" to refer to something at a specific point.


  • Mr. Gump sat on the bench at the bus stop.
  • They met at the airport.

Other examples of prepositions of place include over, under, outside, inside, below, and above.

3. Preposition of Movement

Preposition of movement refers to how something or someone moves from one place to another. It indicates the relationship between location and direction.

The most common preposition in this category is "to," which indicates movement towards a specific destination. Other examples of the preposition of movement include across, off, into, down, and through, to name a few.


  • He went to school every morning until he was 18.
  • Jamie traveled across the world in his jet.
  • The train passed through the tunnel.

4. Preposition of Agents

We use prepositions of agents to connect a nounand a verb. In other words, this type of preposition establishes a causal relationship between the doer and the action.

Common examples of the preposition of agents includes by and with. The word "by" indicates the person acting. Meanwhile, "with" suggests an action with a thing.


  • Oathbringer was written by Brandon Sanderson.
  • She chopped the carrots with a knife.

5. Preposition of Phrases

A preposition of phrases or phrasal preposition refers to a combination of two or more words that function as a preposition. Note that this is not the same as a prepositional phrase.

Examples of words in this category include along with, in reference to, apart from, because of, according to, instead of, and out of.


  • In spite of his incredible skills, Alex lost the game.
  • According to the new rule, you have to play twice.
  • Contrary to popular opinion, Math is easy.

Rules for Using Prepositions in English Grammar

Rules for using prepositions in english grammar

1. A Noun follows a Preposition

A noun or pronounmust always follow prepositions, never a verb. In other words, a verb can't be the object of a preposition, only a noun.


  • The bone was for the dog.

In the sentence, the noun "dog" comes after the preposition "for."

This rule may seem confusing at first. And that's because you may have notices some words that look like verbs following preposition.


  • I like to ride
  • These boots are for hiking.

However, the words "ride" and "hiking" are not acting as a verb. In the first example, "to ride" is part of the infinitive.

An infinitiveoccurs when a verb doesn't act as a verb. Instead, it acts as a noun, adjective, or adverb. Also, an infinitive is made up of two words: to + verb.

That means "to ride" is not an action that the person is performing. It's something that they like doing.

In the second example, "hiking" is a gerund. A gerund is a verb form that functions as a noun. Here, "hiking" refers to boots' function. No one in this sentence is performing the act of hiking.

2. A Preposition Must Have an Object

All prepositions have objects. If you use a preposition in a sentence without an object, it's not a preposition. That's probably an adverb.


  • They sat in the kitchen.
  • There was a doorway before me.

In the first example, the preposition"in" has the object "the kitchen."Meanwhile, in the second example, the preposition "before" has the object "me."

3. Avoid Using Prepositions at the End of Sentences

As said earlier, prepositions must have objects, and a noun follows them. As a result, you'll rarely find them at the end of a sentence.


  • The chair is where I left my phone on.

However, it's acceptable to end a sentence with a preposition in specific circumstances. The preposition isn't extraneous under this exception.

In other words, removing the preposition would change the meaning of the sentence altogether. In the example above, the preposition "on" doesn't contribute to the sentence.


  • I turned the television on.

Removing the word "on" from the end of this sentence will change its meaning. Instead of switching on the set, it would say you turned the television itself.

4. Pair Your Prepositions Properly

Knowing which preposition fits into a specific sentence can be tricky. This is especially true when you're dealing with idioms.

An idiom is a phrase or expression whose figurative meaning is different from the literal meaning of the individual elements. In other words, idioms don't exactly mean what the words say. As a result, some pairing rules for preposition don't apply here.


  • Rey paid for his plane tickets in advance.
  • Cristen works out on average four times a week.

5. Don't Substitute 'have' for 'of'

The idea of confusing "have" for "of" may seem absurd. But, it's not entirely impossible.


  • I should of come over.

The sentence above may sound like something we say all the time, even though that's not the case.


  • I should have come over.

The preposition "of" doesn't link or join any idea in the sentence. Meanwhile, "have" is an essential helping verb.

6. Don't Confuse 'to' Preposition with 'to' Infinitive

Do not confuse an infinitive particle "to" with the preposition "to". If "to" is followed immediately by a simple verb, then it's part of an infinitive— for example, to live, to love, to laugh. On the other hand, if "to" is followed by a noun construction, it's a preposition.


  • We are going to New York.

As simple as it sounds, differentiating a "to" preposition from a "to" infinitive can still be confusing.


  • I used to cook my food.
  • Now, I'm used to cooking for a family.

One easy way to clear this confusion is to use a preposition checker.
