Learning objectives
By the end of this lesson, you should be able to explain the main rules, identify the target forms in real sentences, avoid common errors and apply the rules to unfamiliar examples.
- Understand the core terms and distinctions.
- Study examples in context rather than memorising isolated rules.
- Complete the practice before opening the answer key.
1. What is an adjective?
An adjective describes or classifies a noun or pronoun. It can appear before a noun (a quiet room) or after a linking verb (the room is quiet). Some adjectives can also follow the noun in fixed or formal constructions.
Predicative: The driver is careful.
After an indefinite pronoun: something useful, someone kind.
Not every word after a linking verb is an adjective: “She became a doctor” contains a noun phrase as subject complement; “She became confident” contains an adjective.
2. Common adjective categories and order
Adjectives can express opinion, size, age, shape, colour, origin, material or purpose. When several come before one noun, English tends to follow an order, but long strings are often awkward and should be rewritten.
| Typical order | Example |
|---|---|
| Opinion + size | a beautiful large garden |
| Size + age + colour | a small old brown bag |
| Origin + material + purpose | a Japanese wooden tea box |
These are tendencies, not an inflexible formula for every phrase. Choose the order that sounds natural and put the most useful information first.
3. Comparative and superlative forms
| Base adjective | Comparative | Superlative |
|---|---|---|
| small | smaller | smallest |
| large | larger | largest |
| happy | happier | happiest |
| careful | more careful | most careful |
| good | better | best |
| bad | worse | worst |
| far | farther/further (context-dependent) | farthest/furthest |
Short adjectives often take -er/-est; many longer adjectives use more/most. Spelling changes include big/bigger/biggest and happy/happier/happiest. Usage varies by adjective, so consult a reliable dictionary when unsure.
Correct: easier, the tallest. Avoid using two comparative or superlative markers together.
4. Comparison patterns
- Comparative + than: “This route is shorter than that one.”
- As + adjective + as: “Mina is as careful as Rupa.”
- Not as/so … as: “This bag is not as heavy as that one.”
- The + comparative, the + comparative: “The more you practise, the more confident you become.”
- One of the + superlative + plural noun: “It is one of the most useful books.”
Use a comparison group that makes sense: “older than I am” or the conversational “older than me” are both used. Avoid comparing unlike things, such as “The population of Dhaka is larger than Chittagong”; compare the population with the population.
5. Common errors
- Incorrect: She is more taller than me. Correct: She is taller than me.
- Incorrect: He is the best of the two. Better: He is the better of the two.
- Incorrect: This is the most unique design. Better: This design is unique. (Unique is generally treated as non-gradable in careful formal writing.)
- Incorrect: The weather is more colder today. Correct: The weather is colder today.
Guided practice
Try each item first. Then open the answer key and read the explanation for any answer you missed.
- Identify the adjective: “The narrow road was quiet.”
- Complete: This box is ___ than that one. (heavy)
- Complete: She is the ___ student in the class. (careful)
- Choose: good → better / gooder.
- Correct: “This is more easier.”
- Complete: My room is as ___ as yours. (bright)
- Complete: The ___ you read, the more vocabulary you learn. (much)
- Choose natural order: a wooden old chair / an old wooden chair.
- Complete: It is one of the ___ buildings in town. (tall)
- Which is normally non-gradable in careful usage: unique / small?
- Complete: Rafi is ___ than his brother. (happy)
- Correct the comparison: “The price of this phone is higher than that phone.”
- Choose: the ___ of the two routes (short / shorter / shortest).
- Complete: This test is not as ___ as the last one. (difficult)
- What is the superlative of bad?
Show answer key and explanations
- narrow and quiet — Narrow describes road; quiet describes the road after was.
- heavier — Heavy changes y to i before -er.
- most careful — Many longer adjectives use most for the superlative.
- better — Good has an irregular comparative form.
- This is easier. — Do not combine more with the -er comparative suffix.
- bright — The as…as pattern uses the base adjective.
- more — The comparative pattern is the more…, the more….
- an old wooden chair — Age commonly precedes material.
- tallest — The pattern is one of the + superlative + plural noun.
- unique — Unique means one of a kind, so a comparative is often logically unsuitable.
- happier — Change y to i and add -er.
- The price of this phone is higher than the price of that phone. — Compare price with price, or say “This phone costs more than that phone.”
- shorter — Comparatives commonly compare two items.
- difficult — As…as takes the base adjective.
- worst — Bad has the irregular forms worse and worst.
Revision checklist
- I can explain the main rule in my own words.
- I can identify the target form in a sentence.
- I can explain why a common incorrect example is wrong.
- I can apply the rule in a new sentence.
Do not judge mastery only by a score. If an answer was wrong, identify the rule behind the mistake and practise that pattern again.
