The Noun Phrase
A noun phrase is a group of words centered around a noun, serving to provide more information about that noun. Information within a noun phrase can be positioned before or after the noun itself.
Information Before the Noun:
1. Determiners: Words like “the,” “a,” “an,” “this,” “some,” etc., that come before the noun to indicate specificity or quantity.
In this example, “this” is a determiner indicating specificity, and “horrible” is an adjective that modifies the noun “rubbish.” This demonstrates how determiners and adjectives can be used to provide more information before the noun.
2. Adjectives and Adverbs: Words that describe or modify the noun.
Here, “rich” is an adjective describing the noun “habitat.” It showcases how adjectives contribute to providing additional information before the noun.
Information After the Noun:
1. Prepositional Phrases: Phrases introduced by prepositions (e.g., of, in, for, on, to, with) that provide additional details about the noun.
In this instance, “with submerged rubbish” is a prepositional phrase that gives more information about the noun “sites.” It illustrates the use of prepositional phrases to offer details after the noun.
2. Past Participle Clauses: Clauses that function like relative clauses and use passive verbs to provide information about the noun.
The phrase “contained in the harbor” is a past participle clause that functions as a relative clause, supplying information about the noun “rubbish.” It demonstrates how past participle clauses can be used to convey information after the noun.
3. Present Participle (-ing) Clauses: Clauses that function like relative clauses and use active verbs in the present or past continuous tense.
The phrase “lying on the sea floor” is a present participle clause, functioning as a relative clause, and it uses the active verb “lying” to describe the noun “debris.” This showcases the use of present participle clauses after the noun.
4. To-Infinitive Clauses: Clauses that express purpose or intention and often follow nouns of time, place, manner, or quantity.
In this example, “to expand” is a to-infinitive clause that expresses the purpose of the noun “decision.” It demonstrates how to-infinitive clauses can provide information after the noun.
Using these various structures within the noun phrase allows for a more detailed and nuanced description of the noun, facilitating effective communication and providing context. The sample sentences illustrate how different elements contribute to enriching the information about the nouns by positioning them before or after the noun, showcasing the importance of these grammar principles in constructing comprehensive noun phrases.
