What are the examples of noun markers?

You're likely referring to determiners, which are words that come before nouns to specify them. They are not "noun markers" in the strict sense, but they are essential for understanding the function of nouns in a sentence.

Here are some examples of determiners:

Articles:

* Definite: the (the book, the cat)

* Indefinite: a, an (a book, an apple)

Possessive Adjectives:

* My, your, his, her, its, our, their (my car, your dog)

Demonstrative Adjectives:

* This, that, these, those (this house, those shoes)

Quantifiers:

* Some, any, many, few, several, all, both, enough, much, little (some cookies, many people)

Numbers:

* One, two, three, etc. (one apple, three books)

Other Determiners:

* Each, every, either, neither (each student, every day)

* Whose, what, which (whose car, what time, which book)

Examples:

* The cat sat on the mat. (definite articles)

* My dog is a golden retriever. (possessive adjective, indefinite article)

* This is my house. (demonstrative adjective, possessive adjective)

* I ate some cookies. (quantifier)

* Three people are waiting. (number)

* Every student passed the test. (other determiner)

Important Note: Determiners are essential for understanding the meaning of a noun. They help us to understand if the noun is specific or general, how much or how many there are, and who owns or possesses it.
