nouns

A noun is a word that represents a person, place, thing, or idea.

Dog, cat, elephant.

'Thing' is a common noun that refers to an object or entity.

A proper noun names a specific person, place, or organization and is capitalized (e.g., 'London'), while a common noun refers to general items or concepts (e.g., 'city').

'Dog' is the noun in the sentence.

Collective nouns refer to a group of individuals or things considered as a single unit (e.g., 'team', 'flock').

An abstract noun represents an idea, quality, or state rather than a concrete object (e.g., 'happiness', 'freedom').

'Toothbrush' is an example of a compound noun, formed by combining 'tooth' and 'brush'.

A countable noun is a noun that can be counted (e.g., 'apple', 'car').

An uncountable noun cannot be counted individually and often refers to substances or concepts (e.g., 'water', 'information').
