The friends are planning a trip and comparing two cities.

Nok: 'Should we go to Chiang Mai or Bangkok?'
Somsak: 'Chiang Mai is smaller than Bangkok, but it's quieter.'
Anna: 'And the weather in Chiang Mai is cooler than in Bangkok. I like that.'
Nok: 'But Bangkok is more exciting than Chiang Mai, I think.'
Somsak: 'True. Bangkok has more restaurants too — but it's also more expensive than Chiang Mai.'
Anna: 'Good point. Short words like small, cool, and cheap just add -er. Longer words like exciting and expensive use "more" instead.'
Nok: 'How do I know which rule to use?'
Anna: 'Short words (one syllable, or two ending in -y) add -er: smaller, cooler, happier. Longer words use more + adjective: more exciting, more expensive. And remember — always add "than" when comparing two things!'

Comparatives compare two things. Short adjectives add -er (+than): smaller, cooler, bigger. Longer adjectives use more + adjective (+than): more exciting, more expensive. A few are irregular: good→better, bad→worse. 🔊
