💡 Tips for Students:

- Look for "than" → usually means comparative
- Look for "the" before the noun → usually means superlative
- For short adjectives (1-2 syllables), add -er (comparative) or -est (superlative)
- For longer adjectives (3+ syllables), use more / most instead (e.g., *more beautiful*, *most beautiful*)
