Phrases by Word Type
A phrase is a group of related words that works as a single unit in a sentence but doesn't contain both a subject and a verb working together (that would be a clause). Every phrase has a "head word" that determines its type, and the rest of the phrase modifies or completes that head word. Knowing the different phrase types helps you understand how sentences are built and gives you more control over your own writing.
Noun and Verb Phrases
A noun phrase centers on a noun and includes all the words that modify it: articles, adjectives, even other phrases. It does anything a plain noun can do.
- Can serve as a subject, direct object, indirect object, or complement
- Example: The old red barn stood at the end of the lane. (subject)
- Example: She finally found the answer to the difficult question. (direct object)
A verb phrase includes the main verb plus any helping (auxiliary) verbs. Together, they form the predicate of the sentence.
- Auxiliaries express tense, mood, or voice (has been running, will be chosen, might have known)
- Adverbs can appear inside the verb phrase: has been quickly running
- Example: The children have been playing in the park all afternoon.
Adjective and Adverb Phrases
An adjective phrase is headed by an adjective and modifies a noun or pronoun. It can appear before the noun or after it (as a predicate adjective or a postmodifier).
- Before the noun: An extremely happy child opened the gift.
- After the noun: The man wearing a blue suit is my uncle.
- After a linking verb: She seemed proud of her accomplishment.
An adverb phrase is headed by an adverb and modifies a verb, an adjective, or another adverb. It answers questions like how?, when?, where?, or to what extent?
- Modifying a verb: She spoke quite eloquently during the debate.
- Modifying an adjective: The water was almost unbearably cold.
- A single-word adverb with its own modifier still counts: very carefully
Prepositional Phrases
A prepositional phrase starts with a preposition and ends with a noun or pronoun (called the object of the preposition), along with any modifiers of that object.
- They function as either adjectives or adverbs depending on what they modify:
- Adjective: The book on the top shelf is mine. (modifies book)
- Adverb: We arrived before noon. (modifies arrived)
- Common relationships they express: location (under the table), time (before noon), manner (with enthusiasm), possession (of the teacher)
- Prepositional phrases can nest inside each other: in the middle of the crowded room
Phrases by Verbal
Verbals are verb forms that don't act as the main verb of a sentence. Instead, they function as nouns, adjectives, or adverbs. There are three types: gerunds, infinitives, and participles. Each one can head its own phrase.
Gerund Phrases
A gerund is a verb form ending in -ing that functions as a noun. A gerund phrase includes the gerund plus any objects, complements, or modifiers it carries with it.
- As subject: Swimming in the ocean is refreshing.
- As direct object: She enjoys reading mystery novels.
- As object of a preposition: He's interested in learning new languages.
One tricky point: when you want to show who performs the gerund's action, use a possessive form before it. Compare:
His singing loudly disturbed the neighbors. (correct, formal) Him singing loudly disturbed the neighbors. (common in casual speech, but less precise)
Infinitive Phrases
An infinitive is to + the base form of a verb. An infinitive phrase includes the infinitive plus any objects or modifiers. What makes infinitives versatile is that they can function as nouns, adjectives, or adverbs.
- As noun (subject): To err is human.
- As adjective (modifying a noun): She needs a place to store her books.
- As adverb (expressing purpose): She went to the store to buy milk.
You've probably heard of split infinitives, where an adverb sits between to and the verb: to boldly go. This is widely accepted in modern usage, especially when moving the adverb would sound awkward.
Participial Phrases
A participial phrase uses a present participle (-ing) or past participle (typically -ed or -en) to modify a noun or pronoun. Unlike gerund phrases, participial phrases always work as adjectives.
- Present participle: Laughing heartily, the children ran through the sprinkler.
- Past participle: Exhausted from the long hike, we collapsed into our tents.
- Mid-sentence: The cat, purring contentedly, curled up in my lap.
Watch out for dangling participles. The participial phrase must clearly modify the right noun, or the sentence becomes confusing or unintentionally funny:
Walking through the park, the flowers were beautiful. (Who's walking? The flowers?) Walking through the park, we admired the beautiful flowers. (Clear.)
Other Phrases
Appositive Phrases
An appositive phrase renames or further identifies a nearby noun. Think of it as a built-in definition or label placed right next to the noun it explains.
- Nonessential (extra info, set off by commas): My sister, a talented musician, performed at the concert.
- Essential (needed to identify which one, no commas): The author John Steinbeck wrote many famous novels.
The comma test: if you can remove the appositive and the sentence still makes clear sense, it's nonessential and needs commas. If removing it leaves the reader asking "which one?", it's essential and gets no commas.
Absolute Phrases
An absolute phrase modifies the entire sentence rather than any single word in it. It contains a noun or pronoun followed by a modifier (often a participle), and it's grammatically independent from the main clause.
- Her voice rising, she demanded an explanation.
- The sun having set, we made our way back to camp.
- The team walked off the field, their heads hanging in defeat.
Absolute phrases add vivid detail or set the scene. They're always set off by commas and can appear at the beginning, middle, or end of a sentence. Don't confuse them with participial phrases: a participial phrase modifies a specific noun, while an absolute phrase comments on the whole situation.
