What are prepositions in English?

Prepositions are words like in, at, to, or for that we use before a to show how that noun is related to the rest of the sentence. For example, the preposition can help you decide if a noun is the location of an object, the time of an event, the reason for the action, the direction of movement, or something else.

In this post, we’ll talk about what a prepositional phrase is and how to use them with and nouns. Then, we’ll introduce you to the most important types of prepositional phrases. Along the way, we’ll give you some tips about where you can learn more about English prepositions and their uses.

Let’s jump in and get started!

Did you know that there are about 150 prepositions in English!? We won’t cover all of them in this post, but here is some basic information about prepositions:

• ✅Most prepositions are single words, and they’re usually short. Here are some of the most common prepositions in English: in, at, to, of, from, by, about, with, before, after, and into.

• ✅Some prepositions are more than one word! Here are a few of the most common multi-word prepositions: in front of, next to, on top of, close to, across from, ahead of, due to, along with, and in regard to.

• ✅Some English participles like given, regarding, including, and following, can also be used as prepositions, especially in formal writing.

A prepositional phrase is a group of words that is made of a preposition followed by a or a :

The noun phrase or pronoun that follows a preposition is called the object of the preposition. If the object of the preposition is a personal pronoun, then you use the :

• ✅ The person behind me is wearing strong perfume.

• ❌ The person behind I is wearing strong perfume.

A prepositional phrase can act as an and modify a noun:

A prepositional phrase can also act as an and modify a .

We can also use a prepositional phrase as the subject in a sentence (like a noun), but this is a less common way to use prepositional phrases:

• Under the bed is where I store my winter clothes.

• Before the movie is the best time to buy snacks.

Usually prepositional phrases go after the word or phrase they’re modifying:

However, the prepositional phrase doesn’t always go directly after the verb or noun:

• If the verb has an object, the prepositional phrase will follow the verb and the object, not just the verb:

  verbobjectprepositional phrase

  ❌Marie practiced for an hour the violin.

  ✅Marie practiced the violin for an hour.

  In English, we never put the prepositional phrase between the verb and its object!

• You can put adverbs between a verb and the prepositional phrase:

  ✅We walked quickly across the crowded street.

• Just like an adjective, sometimes a prepositional phrase that describes the subject can follow the verb be:

  nounprepositional phrase

  ✅The meeting is in the conference room.

  But prepositional phrases do not usually follow other linking verbs like seem or look:

  • ❌The meeting seems at 2 p.m.

  • ❌Marianne looks with her friend.

• Some kinds of prepositional phrases can be moved to the beginning of a sentence. Here, the prepositional phrase is followed by a comma:

  Behind me, a girl was talking on her phone.

  You can do this to avoid repetitive sentence structures, to sound more literary, or sometimes to emphasize the prepositional phrase.
