Nouns are words used to name people, places, animals, objects, and concepts. They are a category of words in speech. A noun will almost always be included in a sentence, and they serve a variety of functions. Nouns have multiple roles that they can play, including subject, indirect object, direct object, subject complement, and object complement.

Noun as Subject

A noun often appears at the start of a sentence when it is employed as the subject.

• John was so tired.
• The students submitted their assignments.
• The zoo was closed last week.
• The President gave an impressive speech.
• Paulo is a famous writer.

Noun as object

Nouns are usually employed as objects in the last clause of a sentence.

• He loves birds.
• I bought a new dress.
• My mother prepared some cake.
• She met her sister.
• We joined the class.

Noun as Complement

A noun serves as a complement when it describes or modifies another noun.

• He is a doctor.
• The girl in my class is a baseball player.
• He was appointed as the Prime Minister.

Types of Nouns

Common Noun

Common nouns are terms that designate ambiguous or general individuals, locations, or objects. For instance, the word “girl” is a common noun that denotes a general location, whereas the word “Suzi” denotes a particular location. Only when they are used to start sentences are common nouns capitalised.

Example: School, animals, students, plants, country, street

Proper Noun

Proper nouns assist in identifying a particular person, place, or item. You should capitalise these words. Proper nouns are always used in names and titles, such as the country name Australia and the individual name Judi .

Examples

Concrete Noun

An object that can be felt or seen is referred to as a concrete noun. A tangible noun is used when anything is something you can see, hear, touch, taste, or smell.
