Lesson Overview



In the English language, certain words come together to create meaning. These words, known as adjectives, give us more details about everything we talk about. 

Understanding how adjectives work can help make our speech and writing clearer and more detailed. By adding the right adjectives, we paint a clearer picture and make our ideas easier to understand.

What Is an Adjective?

An adjective is a word that describes or gives more information about a noun (person, place, or thing). These adjectives help us understand what something is like. 

Adjectives can explain color, size, shape, age, or other qualities. They allow us to communicate more clearly and vividly, turning simple ideas into more specific ones.

Example: In the sentence "The old building looked abandoned," "old" is the adjective that describes the noun "building," telling us about its age.

Forms of Adjectives

Adjectives can be used to compare qualities between different subjects that are performing the same action or sharing the same characteristics. There are three degrees of comparison for adjectives:

Positive Degree of Comparison

The positive form of an adjective is used to describe a single subject without making any comparisons. This is the base form of the adjective.

Example: "This movie is exciting."

Comparative Degree of Comparison

The comparative form of an adjective is used when comparing two subjects that share the same quality. This form typically adds -er or uses more or less.

Example: "This movie is more exciting than the one we watched last week."

Superlative Degree of Comparison

The superlative form is used when comparing three or more subjects, indicating that one subject has the highest degree of a quality. This form often adds -est or uses most or least.

Example: "This is the most exciting movie I've seen this year."

Nouns as Adjectives and Adjective as Nouns

Sometimes, a noun can act as an adjective when it describes another noun.

  • Example: I forgot my lunch box at home.
    • Here, lunch is a noun, but it functions as an adjective to describe the type of box.

Similarly, adjectives can be used as nouns, especially when referring to a group of people. This often happens with the + adjective:

  • Example: The brave never back down from a challenge.
    • The adjective brave stands in for "brave people."

This shift also occurs with other commonly used adjective-noun pairs:

  • Example: We have a big final next week.
    • The noun exam is omitted, and final functions as a noun
