My least favorite part of speech is noun. Though the usage of noun is considered as the simple one as it only describes the name of the place, a person or a thing, but when the sentence construction and the grammatical error are concerned, the knowledge of the appropriate usages of noun make a huge difference. The classification of the noun is as follows, Common Noun, Proper Noun, Collective Noun, Abstract Noun, Countable Nouns, and Uncountable Nouns. There are multiple examples of all these nouns mentioned above.
