A Noun is a fundamental linguistic category used to identify a person, place, thing, or abstract idea. In the architecture of a sentence, the noun serves as the primary “building block,” typically functioning as the Subject (the doer) or the Object (the receiver) of an action.
Nouns are classified based on their nature and the entities they represent:
These denote specific, unique entities. They are always capitalized regardless of their position in a sentence.
Examples: Tokyo, William Shakespeare, The Amazon River.
General names for a class of items or beings.
Examples: city, author, river, table.
These refer to intangible concepts, qualities, or states that cannot be perceived through the five senses.
Examples: Courage, integrity, freedom, sorrow, wisdom.
Objects that have a physical presence and can be touched or seen.
Examples: Smartphone, brick, water, oxygen.
A single word that represents a group of individuals or things.
Examples: A jury (group of judges), a colony (of ants), a fleet (of ships).
Refer to raw materials or primary substances used to create other things.
Examples: Gold, cotton, marble, plastic.
In English, the “Number” of a noun indicates its quantity. While the general rule is to add -s, professional grammar requires knowledge of complex variations:
Nouns ending in -s, -sh, -ch, -x, or -z require -es to make them phonetically pronounceable.
Consonant + Y:
Change ‘y’ to -ies (Fly – Flies).
Vowel + Y:
Simply add -s (Key – Keys).
Consonant + O:
Usually add -es (Hero – Heroes, Potato – Potatoes).
Some nouns do not use suffixes; instead, they change their internal structure:
Some nouns have no singular form and always take a plural verb.
Examples: Scissors, spectacles, trousers, goods, alms.
Some nouns end in ‘-s’ but are treated as singular.
Examples: Mathematics, Physics, News, Ethics, Billiards.
These cannot be pluralized and do not take ‘a’ or ‘an’.
Examples: Advice, information, luggage, poetry, furniture.
Incorrect: “He gave me many advices.”
Correct: “He gave me much advice” or “pieces of advice.”
