Comparative and superlative
- Short words: add -er/-est – tall, taller, tallest.
- Long words: use more/most – careful, more careful, most careful.
Irregular forms
- good → better → best; bad → worse → worst.
Key idea
Use -er/-est for short adjectives and more/most for long ones; some are irregular (good/better/best).
Remember
Use 'than' with comparatives: taller than.
