What is a nonspecific nouns?

There's no such thing as a "nonspecific noun." The term you're likely thinking of is common noun.

Common nouns refer to general categories of people, places, things, or ideas. They are not specific to any particular individual or item.

Here are some examples of common nouns:

* People: teacher, student, doctor, friend

* Places: city, country, park, school

* Things: book, car, chair, phone

* Ideas: happiness, love, freedom, justice

Proper nouns, on the other hand, refer to specific people, places, things, or ideas. They are always capitalized.

Here are some examples of proper nouns:

* People: John Smith, Queen Elizabeth II, Albert Einstein

* Places: New York City, Mount Everest, Australia

* Things: iPhone, Mona Lisa, the Declaration of Independence

* Ideas: Buddhism, Christianity, Communism

So, while the term "nonspecific noun" isn't a real grammatical term, it likely refers to the broader category of common nouns, which are used to refer to general categories rather than specific individuals or items.
