Definition of Noun : A noun, or noun substantive, is a word or phrase that refers to a person, place, thing, event, substance or quality. Nouns are parts of speech and can be classified in different ways such as proper nouns (e.g. "Janet") versus common nouns (e.g. "girl"), or collective nouns (e.g. "bunch", "herd"). Nouns can be substituted by pronouns (e.g. "she" and "which"). The word noun derives from Latin nomen meaning "name" (as a noun can be considered an object, person, or concept's name).
Two important things to remember when using noun :
(a) Is it singular or plural
(b) Is it countable or uncountable
If that noun is delegating only one thing, do not put 's' at the end of that noun.

Notes : There must be 'a' before noun that delegating only one thing.
a dog (only one dog)
If there is more than one dog, put 's' at the end of that noun.
