Introduction
Comparisons and adjectives are essential tools for describing differences and similarities between people, things and actions. This guide explains comparative and superlative forms, how to compare actions, how to form adjectives from nouns and verbs, and how to use -ed and -ing adjective pairs to describe feelings and causes. Clear examples and practice tips are provided to help you use these structures accurately in academic and everyday contexts.
Comparatives: comparing two items
Definition: A comparative form shows how two people or things differ in degree or quality.
- Forming comparatives
- Short adjectives (one syllable, sometimes two): add -er. Example: small → smaller.
- Long adjectives (two or more syllables): use more / less + adjective. Example: beautiful → more beautiful / less beautiful.
- Irregular: good → better, bad → worse.
Examples:
- He is taller than his teammate.
- This problem is more difficult than the last one.
- Expressing the size of a difference
- Small difference: use modifiers like a bit, slightly. Example: She is a bit taller than me.
- Large difference: use much, so much, a lot, far, far too. Example: He is much calmer than his rival.
- Comparing actions (adverbs)
- Use more / less + adverb for long adverbs or when clarity is needed. Example: They played more confidently than their opponents.
- Comparative structure with results
- Use paired comparatives to show cause/result: The longer ... , the more ....
- Example: The longer the championship went on, the more confident Fischer became.
💡 Věděli jste?Fun fact: Native speakers often stress words like "much" or "a bit" to show the exact size of the difference in speech.
Equal comparisons and negatives
Definition: Use "as + adjective + as" to say two things are equal in a quality.
- Affirmative: She is as tall as her sister.
- Commonly used with a negative to show inequality: He wasn't as traditional as his rival.
Superlatives: comparing more than two
Definition: A superlative form compares one item to all others in a group.
- Forming superlatives
- Short adjectives: add -est. Example: big → biggest.
- Long adjectives: use the most / the least + adjective. Example: interesting → the most interesting.
- Irregular: good → the best, bad → the worst.
- Emphasising large differences
- Use by far to emphasise an extreme difference. Example: It's by far the most famous chess match ever.
Table: Comparative vs Superlative forms
| Comparison type | Short adjective | Long adjective | Emphasis example |
|---|---|---|---|
| Comparative | small → smaller | important → more important | much calmer, a bit taller |
| Superlative | small → smallest | important → the most important | by far the most famous |
Forming adjectives from nouns and verbs
Definition: Add a suffix to a noun or verb to create an adjective that describes a quality.
Common suffixes and examples:
- -al: traditional, logical
- -ful: colourful, successful
- -ic: allergic, historic
- -ish: foolish, nightmarish
- -less: useless, pointless
- -ous: poisonous, dangerous
- -able / -ible: acceptable, doable
- -y: meaty, scary
Notes:
- Spelling changes may be required (e.g., hope → hopeful, sense → sensible).
- Some adjective forms change meaning from the base word (childish is negative; childlike is different).
- Some nouns/verbs have two adjective forms with distinct meanings (economic vs economical; historic vs historical).
Practice tip: When forming adjectives, say the new word aloud to check naturalness and meaning.
-ed and -ing adjective pairs (feelings vs causes)
Definition: -ed adjectives describe a person’s feeling; -ing adjectives describe the thing or situation that causes that feeling.
Examples:
- I feel bored (an -ed adjective — my feeling). The film is boring (an -ing adjective — the cause).
- I was astonished by the result. The result was astonishing.
Common pairs:
- alarmed / alarming
- as
