A prepositional phrase goes from a preposition to a noun. There can be an article and/or adjective in the middle.
| Preposition | Article and/or Adjective | Noun (or pronoun) |
| to | school | |
| for | my | sister |
| with | a large blue | bag |
| about | the | grammar |
| to | the | airport |
| under | her | bed |
| on | the white | table |
| for | me |
A prepositional phrase can go before or after the subject-verb-object, or both before and after. Usually, when the prepositional phrase is first, it is a time phrase. It is more common for the prepositional phrases to be after the subject-verb-object.
- After lunch, we usually buy a cup of coffee
- She drives her carto school.
- Until 2015 I lived in my country.
- He didn’t speak English in 2019 before this class.
Sometimes, a prepositional phrase can act as an adjective, describing a noun:
- The student in the blue hat wants my attention.
- That car with a white top looks amazing!
You can use many prepositional phrases in one sentence!
- In the morning after her coffee she sits down at the computer and works on her students’ homework on Canvas until lunchtime.
