Noun Definition
In order to understand what a noun is, the most simple explanation is that a noun is a word which is used to refer to a person, item, thing or place. In every sentence in English, there must be a subject and that subject will always be a noun. However, the noun can also play other parts within a sentence such as the indirect or direct object, object or subject complement, adjective or appositive. This means that every sentence you create will feature a noun, making this one of the most important aspects of English grammar.
