📚 Quick Lesson

✨ What are Comparatives?

We use comparatives to compare two things and show the difference between them.

📏 Rule 1: One-Syllable Adjectives

Add -er to the end: tall → taller | fast → faster | cold → colder
Special: If the word ends in one vowel + one consonant, double the last letter: big → bigger, hot → hotter

🎯 Rule 2: Adjectives Ending in -y

Change -y to -ier: happy → happier | easy → easier | pretty → prettier | busy → busier

📚 Rule 3: Long Adjectives (2+ syllables)

Put "more" before the adjective: beautiful → more beautiful | expensive → more expensive | difficult → more difficult

⚡ Rule 4: Irregular Forms (Memorize These!)

good → better | bad → worse | far → farther/further | little → less | many/much → more

🔢 Rule 5: Comparing Quantities (Nouns)

MORE + noun (countable or uncountable):
• I have more books than you. | She drinks more coffee than me.

FEWER + countable nouns (things you can count):
• There are fewer students in this class than last year. | He made fewer mistakes this time.

LESS + uncountable nouns (things you cannot count):
• We have less time than before. | This costs less money. | I need less sugar in my tea.
