Grammatical Functions of English Prepositions and Prepositional Phrases

Traditional grammars define prepositions as words that “link to other words, phrases, and clauses” and that “express spatial or temporal relations.” Prepositional phrases are phrases that consist of a preposition plus another word, phrase, or clause functioning as a prepositional complement. Prepositions and prepositional phrase perform seven primary grammatical functions within sentences in the English language. The seven primary functions of prepositions and prepositional phrases are:

  1. Prepositional phrase head
  2. Noun phrase modifier
  3. Noun phrase complement
  4. Adjective phrase complement
  5. Verb phrase complement
  6. Adjunct adverbial
  7. Disjunct adverbial

Prepositions as Prepositional Phrase Heads

The first primary grammatical function that prepositions perform is the prepositional phrase head. A prepositional phrase consists of a preposition plus another phrase or clause that functions as the prepositional complement. For example, the following italicized prepositions function as prepositional phrase heads:

  • in the library
  • after reading the book
  • for whatever will repair the leak

Prepositional Phrase as Noun Phrase Modifiers

The second primary grammatical function that prepositional phrases perform is the noun phrase modifier. A noun phrase modifier is a word, phrase, or clause that modifies or describes a noun including a noun phrase. For example, the following italicized prepositional phrases function as noun phrase modifiers:

  • the puppy with the blue and white fur
  • an old man with glasses
  • someone for whom the bell tolls

Prepositional Phrase as Noun Phrase Complement

The third primary grammatical function that prepositional phrases perform is the noun phrase complement. A noun phrase complement is a word, phrase, or clause that completes the meaning of a noun phrase. For example, the following italicized prepositional phrases function as noun phrase complements:

  • passion for reading
  • love of the game
  • fear of flying

Prepositional Phrase as Adjective Phrase Complement

The fourth primary grammatical function that prepositional phrases perform is the adjective phrase complement. An adjective phrase complement is a word, phrase, or clause that completes the meaning of an adjective phrase. For example, the following italicized prepositional phrases function as adjective phrase complements:

  • fond of bananas
  • afraid of falling down the stairs
  • aware of the dire consequences

Prepositional Phrase as Verb Phrase Complement

The fifth primary grammatical function that prepositional phrases perform is the verb phrase complement. A verb phrase complement is a word, phrase, or clause that completes the meaning of a verb phrase. For example, the following italicized prepositional phrases function as verb phrase complements:

  • rely on my husband
  • listen to the music
  • approve of my plan

A verb with a verb phrase complement is often referred to as a prepositional verb. Prepositional verbs are a common verb form in the English language that consist of a verb followed by a preposition.

Prepositional Phrase as Adjunct Adverbial

The sixth primary grammatical function that prepositional phrases perform is the adjunct adverbial. An adjunct adverbial is a word, phrase, or clause that modifies an entire clause by providing additional information about time, place, manner, condition, purpose, reason, result, and concession. For example, the following italicized prepositional phrases function as adjunct adverbials:

  • The children waited in line.
  • The couple is walking their dog along the beach.
  • She failed the test because of her illness.

Prepositional Phrase as Disjunct Adverbial

The seventh primary grammatical function that prepositional phrases perform is the disjunct adverbial. A disjunct adverbial provides additional information to frame an entire clause. For example, the following italicized prepositional phrases function as disjunct adverbials:

  • In my opinion, learning about grammar is fun.
  • For the love of goodness, the children need to stop whining.
  • With all due respect, you need to calm down.
