Look at these three sentences: "Ravi is tall." "Ravi is taller than Amit." "Ravi is the tallest boy in the class." All three sentences use the adjective "tall," but in different forms. When we compare people, animals, or things, we change the form of the adjective. These different forms are called degrees of comparison.
Every adjective has three degrees:
1. Positive Degree -- describes one person or thing without comparing. Example: "This mango is sweet."
2. Comparative Degree -- compares two persons or things. We usually add -er. Example: "This mango is sweeter than that one."
3. Superlative Degree -- compares three or more persons or things. We usually add -est. Example: "This is the sweetest mango in the basket."
Rule 1: Short adjectives (one syllable) -- Add -er for comparative and -est for superlative.
tall -- taller -- tallest | small -- smaller -- smallest | long -- longer -- longest
Rule 2: Adjectives ending in -e -- Add only -r or -st.
large -- larger -- largest | brave -- braver -- bravest | fine -- finer -- finest
Rule 3: Short adjectives ending in a consonant after a single vowel -- Double the last letter, then add -er / -est.
big -- bigger -- biggest | hot -- hotter -- hottest | thin -- thinner -- thinnest | fat -- fatter -- fattest
Rule 4: Adjectives ending in -y -- Change y to i, then add -er / -est.
happy -- happier -- happiest | easy -- easier -- easiest | heavy -- heavier -- heaviest | lazy -- lazier -- laziest
Rule 5: Long adjectives (two or more syllables) -- Use more for comparative and most for superlative.
beautiful -- more beautiful -- most beautiful | careful -- more careful -- most careful
Some adjectives do not follow any rule. Their forms change completely. You must learn them by heart.
