What are the different types of noun phrases? Explain each type with examples.

Noun phrases are groups of words that function as nouns in a sentence. They consist of a noun or pronoun as the head, along with modifiers, determiners, and other words that provide additional information about the noun. There are several types of noun phrases, each serving a different purpose in a sentence. Let's explore each type with examples:

1. Simple Noun Phrases:
These noun phrases consist of a single noun or pronoun without any modifiers or determiners. They are the most basic form of noun phrases.
Example: "Dog" or "She"

2. Compound Noun Phrases:
Compound noun phrases are formed by combining two or more nouns together. They can be joined by a conjunction or hyphen.
Example: "Sister-in-law" or "Coffee table"

3. Determiner Phrases:
Determiner phrases include a determiner before the noun. Determiners are words like "the," "a," "an," "this," "that," etc.
Example: "The cat" or "An apple"

4. Prepositional Phrases:
Prepositional phrases consist of a preposition followed by a noun phrase. They provide information about location, time, direction, or manner.
