Definition

What is it?

A compound adjective is an adjective made up of two or more words, usually joined by hyphens, that act as a single idea to describe a noun. It tells us more about the noun, just like a regular adjective, but uses a combination of words.

Simple Example

Quick Example

Imagine you see a 'ten-rupee note'. Here, 'ten-rupee' is a compound adjective describing the note. It's not just 'ten' and 'rupee' separately; it's one idea telling you the value of the note.

Worked Example

Step-by-Step

Let's find the compound adjective in the sentence: 'My cousin won a well-deserved trophy for the inter-school competition.'

Step 1: Identify the nouns in the sentence. Nouns are 'cousin', 'trophy', 'competition'.
---Step 2: Look for words that describe these nouns. 'My' describes 'cousin'. 'Well-deserved' describes 'trophy'. 'Inter-school' describes 'competition'.
---Step 3: Check if any of these descriptive words are made of two or more words joined by a hyphen. 'Well-deserved' has 'well' and 'deserved' joined by a hyphen. 'Inter-school' has 'inter' and 'school' joined by a hyphen.
---Step 4: Confirm they act as a single idea. 'Well-deserved' acts as one adjective telling us *how* the trophy was deserved. 'Inter-school' acts as one adjective telling us *which* competition.
---Answer: The compound adjectives are 'well-deserved' and 'inter-school'.

Why It Matters

Understanding compound adjectives makes your writing clearer and more precise, which is crucial in fields like journalism, law, and technical writing. Clear communication helps you express complex ideas simply, whether you're writing a news report or explaining a scientific discovery.

Common Mistakes

MISTAKE: Forgetting hyphens when the compound adjective comes before the noun (e.g., 'a well known author') | CORRECTION: Always use hyphens for compound adjectives before a noun (e.g., 'a well-known author')

MISTAKE: Hyphenating compound adjectives when they come after the noun (e.g., 'The author was well-known.') | CORRECTION: Usually, do not hyphenate when the compound adjective comes after the noun (e.g., 'The author was well known.')

MISTAKE: Adding an 's' to number-based compound adjectives (e.g., 'a five-years plan') | CORRECTION: The noun part of a number-based compound adjective is always singular (e.g., 'a five-year plan')

MCQ

Quick Quiz

Which sentence correctly uses a compound adjective?

She is a good natured person.

He bought a ten rupee note.

The well-known scientist visited our school.

My friend is a quick thinking boy.

The Correct Answer Is:

Option C uses 'well-known' with a hyphen because it comes before the noun 'scientist' and acts as a single adjective. Options A, B, and D are missing hyphens in their compound adjectives.

Real World Connection

In the Real World

Journalists writing news headlines often use compound adjectives to convey information quickly and concisely. For example, a headline might read 'Record-breaking Cricket Match' or 'Budget-friendly Mobile Phone Launched'. This helps readers understand the main point at a glance, just like when you quickly scan a cricket score or a product review online.
