Formation of Adjectives from Nouns
Many adjectives are formed by adding a suffix to a noun. This process helps you describe qualities or features related to that noun. For example, the noun “child” becomes the adjective “childish.” Learn these patterns for better writing and speaking.
- Luck + y → Lucky
- Rain + y → Rainy
- Magic + al → Magical
- Tragedy + ic → Tragic
- Care + ful → Careful

- Depend + able → Dependable
- Amuse + ing → Amusing
- Tire + less → Tireless
- Forget + ful → Forgetful
- Create + ive → Creative

FAQs on Formation of Adjectives: How to Make Adjectives from Nouns & Verbs
1. What is the formation of adjectives in English grammar?
The formation of adjectives involves creating descriptive words that modify nouns. This is often done by adding suffixes to nouns or verbs, changing their part of speech. Understanding adjective formation improves descriptive writing and grammar skills.
2. How are adjectives formed from nouns and verbs?
Adjectives from nouns are typically formed by adding suffixes like -y (sunny), -al (magical), -ful (careful), -ous (dangerous), -ic (artistic), or -ish (childish). Adjectives from verbs often use suffixes such as -able (breakable), -ive (talkative), or -ing (amazing).
3. What are the most common suffixes for adjective formation?
Some of the most common adjective suffixes include:
- -able/-ible (e.g., breakable, edible)
- -al (e.g., magical, musical)
- -ful (e.g., beautiful, helpful)
- -ic (e.g., artistic, scientific)
- -ish (e.g., childish, reddish)
- -ive (e.g., active, creative)
- -less (e.g., careless, hopeless)
- -ous (e.g., famous, dangerous)
- -y (e.g., happy, sunny)
4. What is an example of the formation of adjectives?
The noun “beauty” becomes the adjective “beautiful” by adding the suffix “-ful.” Similarly, the verb “to depend” forms the adjective “dependable” with the suffix “-able.”
5. Are there irregular rules for adjective formation?
Yes, some adjective formations are irregular and don't follow standard suffix rules. For instance, 'good' becomes 'better' and 'best' for comparative and superlative forms, while 'bad' changes to 'worse' and 'worst'. Learning these exceptions is crucial for correct grammar.
6. Can a single root word have multiple adjective forms with different meanings?
Yes, a single root word can have multiple adjective forms with distinct meanings. For example, the root word 'happy' can form adjectives like 'happily' (adverb) and 'happiness' (noun). These variations demonstrate the rich flexibility of English morphology.
7. Which suffixes change spelling rules (like ‘y’ to ‘i’ in “happy” → “happiness”, “happy” → “happy”)?
Suffixes like -ness, -ful, -ous, and -able often trigger spelling changes. A final -y often changes to -i before these suffixes (happy → happiness, happy → happily). Other suffixes may lead to the dropping of a final -e. It's crucial to learn these morphological rules to avoid spelling mistakes.
8. How does adjective formation affect the meaning and tone of a sentence?
Adjective formation significantly impacts a sentence's meaning and tone. Using different suffixes can add nuance to descriptions. For example, 'careful' has a positive connotation, while 'careless' has a negative one. Selecting the correct adjective enhances clarity and precision.
9. What are common mistakes students make with derived adjectives on board exams?
Common errors include incorrect suffix application, misspellings due to irregular forms, and confusion between adjective and adverb forms. Careless adjective formation can lead to grammatical errors and loss of marks in exams.
10. How do I quickly identify whether to form an adjective or use another part of speech?
Consider the word's function in the sentence. Does it directly modify a noun or pronoun? If yes, an adjective is likely needed. If not, it might be an adverb, verb, or another part of speech. Understanding the semantic role of words is key.
11. How can I visually memorize tricky adjective suffix patterns for long-term retention?
Use flashcards, mind maps, or tables to organize and visualize adjective suffixes and their associated spelling rules. Grouping similar patterns enhances memory and recall. Practice using them in sentences to reinforce learning.
12. What are some examples of compound adjectives?
Compound adjectives are formed by combining two or more words to describe a noun. Examples include 'well-known,' 'long-lasting,' 'heart-breaking,' 'world-famous,' and 'easy-going.' These are often hyphenated to avoid ambiguity.
