Grammar: Prepositions

Preposition Basics

preposition is a word or group of words used before a noun, pronoun, or noun phrase to show direction, time, place, location, spatial relationships, or to introduce an object. Some examples of prepositions are words like in, at, on, of, and to.

Prepositions in English are highly idiomatic. Although there are some rules for usage, much preposition usage is dictated by fixed expressions. In these cases, it is best to memorize the phrase instead of the individual preposition.

A Few Rules

Prepositions of Direction

To refer to a direction, use the prepositions to, (in)to, and on(to).

  • She drove to the store.
  • Don’t ring the doorbell. Come right in(to) the house.
  • Drive on(to) the grass and park the car there.

 

Prepositions of Time

To refer to one point in time, use the prepositions in, at, and on.

Use in with parts of the day (not specific times), months, years, and seasons.

  • He reads in the evening.
  • The weather is cold in December.
  • She was born in 1996.
  • We rake leaves in the fall.

Use at with the time of day. Also use at with noon, night, and midnight.

  • I go to work at 8:00.
  • He eats lunch at noon.
  • She often goes for a walk at night.
  • They go to bed at midnight.

Use on with days.

  • I work on Saturdays.
  • He does laundry on Wednesdays.

To refer to extended time, use the prepositions since, for, by, during, from…to, from…until, and (with)in.

  • I have lived in Minneapolis since 2005. (I moved there in 2005 and still live there.)
  • He will be in Toronto for 3 weeks. (He will spend 3 weeks in Toronto.)
  • She will finish her homework by 6:00. (She will finish her homework sometime between now and 6:00.)
  • He works part time during the summer. (For the period of time throughout the summer.)
  • I will collect data from January to June. (Starting in January and ending in June.)
  • They are in school from August until May. (Starting in August and ending in May.)
  • She will graduate within 2 years. (Not longer than 2 years.)

 

Prepositions of Place

To refer to a place, use the prepositions in (the point itself), at (the general vicinity), on (the surface), and inside (something contained).

  • They will meet in the lunchroom.
  • She was waiting at the corner.
  • He left his phone on the bed.
  • Place the pen inside the drawer.

To refer to an object higher than a point, use the prepositions over and above. To refer to an object lower than a point, use the prepositions below, beneath, under, and underneath.

  • The bird flew over the house.
  • The plates were on the shelf above the cups.
  • Basements are dug below ground.
  • There is hard wood beneath the carpet.
  • The squirrel hid the nuts under a pile of leaves.
  • The cat is hiding underneath the box.

 To refer to an object close to a point, use the prepositions by, near, next to, between, among, and opposite.

  • The gas station is by the grocery store.
  • The park is near her house.
  • Park your bike next to the garage.
  • There is a deer between the two trees.
  • There is a purple flower among the weeds.
  • The garage is opposite the house.

 

Prepositions of Location

To refer to a location, use the prepositions in (an area or volume), at (a point), and on (a surface).

  • They live in the country. (an area)
  • She will find him at the library. (a point)
  • There is a lot of dirt on the window. (a surface)

 

Prepositions of Spatial Relationships

To refer to a spatial relationship, use the prepositions above, across, against, ahead of, along, among, around, behind, below, beneath, beside, between, from, in front of, inside, near, off, out of, through, toward, under, and within.

  • The post office is across the street from the grocery store.
  • We will stop at many attractions along the way.
  • The kids are hiding behind the tree.
  • His shirt is off.
  • Walk toward the garage and then turn left.
  • Place a check mark within the box.

Prepositions Following Verbs and Adverbs

Some verbs and adjectives are followed by a certain preposition. Sometimes verbs and adjectives can be followed by different prepositions, giving the phrase different meanings. To find which preposition(s) follow(s) the verb or an adjective, look the verb or adjective up in an online dictionary, such as Merriam Webster, or use a corpus, such as The Corpus of Contemporary American English. Memorizing these phrases instead of just the preposition alone is the most helpful.

Ending a Sentence With a Preposition

At one time, schools taught students that a sentence should never end with a preposition. This rule is associated with Latin grammar, and while many aspects of Latin have made their way into English, there are times when following this particular grammar rule creates unclear or awkward sentence structures. Since the purpose of writing is to clearly communicate your ideas, it is acceptable to end a sentence with a preposition if the alternative would create confusion or is too overly formal.

Example: The car had not been paid for. (Ends with a preposition but is acceptable)

Unclear Revision: Paid for the car had not been. (Unclear sentence.)

 

Example: I would like to know where she comes from. (Ends with a preposition but is acceptable)

Overly Grammatical Revision: I would like to know from where she comes. (Grammatical but overly formal. Nobody actually speaks like this.)

 

However, in academic writing, you may decide that it is worth revising your sentences to avoid ending with a preposition in order to maintain a more formal scholarly voice.

Example: My research will focus on the community the students lived in.

Revision: My research will focus on the community in which the students lived.

 

Example: I like the people I am working with.

Revision: I like the people with whom I am working.

Prepositional Phrases and Wordiness

Like with pronouns, too many prepositional phrases can create wordiness in a sentence:

Example: The author chose the mixed-method design to explain that the purpose of the study was to explore the leadership qualities of the principals in the schools as a means to gauge teacher satisfaction in the first year of teaching.

This type of sentence could be shortened and condensed to minimize the prepositional phrases and bring clarity to the writer's intent:

Revision: The author chose the mixed-method design to explore the principals' leadership qualities and their impact on first-year teachers' satisfaction.

Unnecessary Prepositions

If the preposition is unnecessary, leave it out. This creates more clear and concise writing.

Example: Where are the plates at?

Revision: Where are the plates?

 

Example: She jumped off of the balance beam.

Revision: She jumped off the balance beam.
