​What is a preposition?

Preposition (noun): a part-of-speech usually coming BEFORE a noun phrase and connecting it to another part of the sentence.

​

A preposition is a word used to link nouns, pronouns, or phrases to other words within a sentence. They act to connect the people, objects, time and locations of a sentence.  Prepositions are usually short words, and they are normally placed directly in front of nouns. In some cases, you’ll find prepositions in front of gerund verbs.

​

A nice way to think about prepositions is as the words that help glue a sentence together. They do this by expressing position and movement, possession, time and how an action is completed.​

​

Form

Prepositions have no particular form. The majority of prepositions are single words, but some are two- or three-word phrases:

• one-word prepositions (before, into, on)

• complex prepositions (according to, but for, in spite of)

Let's see some examples!

​Examples of Prepositions

Look at these example sentences:

• The book is on the round table. (relationship in space)

• We will meet in November. (relationship in time)

• I sent the information by email. (relationship of method)

Several other relationships are expressed by prepositions. In addition, more metaphorical ideas can be expressed such as: in love, beyond doubt, under investigation

If a preposition does not come BEFORE another word, it is still closely linked to another word:

• Who did you talk to?

• To whom did you talk?

• I talked to Jane.
