What is the difference between Common Noun and Proper Noun?

Any word which bears the name of any generic term or non-specific categories is are Common Noun. The first letters are generally not capitalised and are used with Articles or Determiners. These words refer to a broad category and do not have a specific significance, unlike Proper Nouns.

Yes, apart from Proper Noun, all other forms of Nouns, including Collective Noun, Concrete Noun, Abstract Noun, Countable Noun, etc. can be Common Nouns. As long as they do not refer to anything specific, all these types of Nouns can be considered Common Noun.

Common Noun is one of the nine types of Nouns, which denotes the name of a group or a type of existing phenomenon. Like the name suggests, Common Nouns refer to any living or non-living beings, places, or abstract ideas or thoughts. As long as a word is not named anything specific, it is considered to be a Common Noun.

Demonstrative pronouns are words used to point toward specific people, objects, or ideas without directly naming them.

Most common ones are this, that, these, and those. They help the speaker or writer indicate whether something is near or far, and whether it is singular or plural. For example, “This is my bag” or “Those are your shoes.” They are widely used in daily communication to bring clarity and emphasis.
