What are Adjectives in English?
An adjective is a word that describes or modifies a noun — it tells us about size, colour, shape, age, origin, material, or quality. 'A steep hill', 'an unexpected decision', 'the bright yellow taxi'. Every noun can be described by one or more adjectives.
In English, adjectives appear in two positions: directly before the noun they modify (attributive: 'a heavy bag'), or after a linking verb like be, seem, look, or feel (predicative: 'the bag is heavy'). Both positions are grammatically standard and carry the same meaning.
Adjectives also change form to make comparisons. Short adjectives add -er and -est; longer adjectives use more and most. A small group of very common adjectives have entirely irregular comparative and superlative forms — good → better → best, bad → worse → worst — that must be memorised.
Adjective Comparison Forms
The choice between adding -er/-est and using more/most depends mainly on the number of syllables. Adjectives with two or more syllables almost always use more/most. Adjectives with irregular comparison forms must be memorised.
Adjective → comparative (-er / more ___) → superlative (-est / most ___)Regular Comparison Rules
| Adjective type | Comparative | Superlative |
|---|---|---|
| 1 syllable (tall) | Add -er: taller | Add -est: tallest |
| 1 syllable ending -e (nice) | Add -r: nicer | Add -st: nicest |
| 1 syllable ending consonant-vowel-consonant (big) | Double consonant + -er: bigger | Double consonant + -est: biggest |
| 2 syllables ending -y (happy) | Change -y to -ier: happier | Change -y to -iest: happiest |
| 2+ syllables (careful) | more careful | most careful |
Irregular Comparison Forms
These forms do not follow any spelling rule — learn them as adjective / comparative / superlative triples.
| Adjective | Comparative | Superlative |
|---|---|---|
| good | better | best |
| bad | worse | worst |
| far | farther / further | farthest / furthest |
| little | less | least |
| much / many | more | most |
How Adjectives Work
Attributive Position — Before the Noun
When an adjective appears directly before the noun it describes, it is in attributive position. This is the most natural and common placement.
- She handed him a thick envelope without any explanation.
- The project required careful planning and a substantial budget.
- He ordered a strong coffee and a warm croissant before the meeting.
Predicative Position — After a Linking Verb
When an adjective follows a linking verb (be, seem, look, feel, smell, taste, sound, become, appear), it is in predicative position and describes the subject, not the verb.
- The proposal seems reasonable to most of the board.
- After the hike, everyone felt exhausted.
- The broth tastes too salty — did you add extra?
Comparative — Comparing Two Things
Use the comparative form to compare exactly two nouns. Always pair the comparative with 'than'.
- The second proposal was more detailed than the first.
- This version is stronger than the one we submitted last quarter.
- Her new office is closer to the station than her old one.
Superlative — The Extreme of a Group
Use the superlative to rank one noun at the top or bottom of a group of three or more. Always use 'the' before the superlative form.
- It was the most complex case the firm had handled in a decade.
- Nairobi was the hottest place she had visited on the entire trip.
- He gave the shortest speech of the evening — and the most memorable.
Patterns That Signal an Adjective
Adjective vs Adverb
The most frequent adjective error at every level is using an adjective where an adverb is needed, or vice versa. The key question: are you describing a noun, or describing how an action happens?
Adjective — describes a noun
She gave a <hl>clear</hl> explanation of the process.
Clear is an adjective. It describes the noun 'explanation'.
Adverb — describes a verb
She explained the process <hl>clearly</hl>.
Clearly is an adverb. It describes the verb 'explained' — how she explained.
Adjective after linking verb — correct
The result <hl>looks good</hl>.
Good is an adjective. 'Looks' is a linking verb connecting subject to description.
Adverb after action verb — correct
She performed <hl>well</hl>.
Well is the adverb form of good. It describes the action verb 'performed'.
Common Mistakes
Using an adverb instead of adjective after a linking verb
✗ The plan sounds interestingly.
✓ The plan sounds interesting.
After a linking verb (looks, sounds, seems, feels, tastes, smells), use an adjective — not an adverb. The adjective describes the subject, not the verb.
Double comparative or superlative
✗ This route is more faster than the other one.
✓ This route is faster than the other one.
Never combine -er with more, or -est with most. Short adjectives take -er/-est; long adjectives take more/most. Choosing both at once is always wrong.
Missing 'the' before a superlative
✗ She is most talented designer on the team.
✓ She is the most talented designer on the team.
Superlatives always require 'the' in front of them. The article signals that one specific thing is being identified as the extreme within a defined group.
Wrong adjective order
✗ He drives an Italian old black sports car.
✓ He drives an old black Italian sports car.
English adjectives follow a fixed sequence before a noun: opinion → size → age → shape → colour → origin → material → purpose. Age (old) comes before colour (black), which comes before origin (Italian).
