What are some examples of common nouns?

Hint: A generic name for a person, location, or thing in a class or category is a common noun. A common noun is not capitalised until it starts a sentence or appears in a title, unlike proper nouns. Common nouns may be concrete (perceptible to the senses), abstract (involving general concepts or qualities), or collective nouns (referring to a group or collection).

Complete answer:
A noun is a word that refers to a single object or a group of objects, such as living beings, places, behaviours, qualities, life stages, or ideas. Noun, on the other hand, is not a semantic category, so it cannot be categorised based on its meaning. Verbs can express actions and states of being, adjectives can express virtues, and adverbs can express locations.

A common noun refers to a class of entities (city, world, human, etc.) and can be used to refer to instances of that class (a city, these persons, our corporation). The common nouns are not written in capital letters because they do not represent any specific person or thing. They are written in capital letters only when they start a sentence.
For example: “The dog is sitting under the tree.” In this sentence, “dog’ is the common noun since it does not refer to any specific dog.

Note: In English, nouns are possibly second only to verbs as an integral part of speech. It's difficult to say much without resorting to the use of a noun. Nouns in English come in a variety of forms. It's helpful to know what kind of noun a noun is because different forms have different rules.
