English Intermediate I: U3:Comparative and Superlative Adjectives

Comparatives and Superlatives

Comparatives are used to show the difference between two objects. Let’s say that I have two cars. I have a little Toyota and a big Ford. A comparative is used to show the difference between the two. The Ford is big so we can say “the Ford is bigger than the Toyota”. Because the Toyota is small, we can say “The Toyota is smaller than the Ford”. To learn to use these we need to learn five basic rules.

Superlatives are used to show the difference between more than two objects. Let’s say that I have three cars. I have a little Toyota, a medium size Jeep and a big Ford. A superlative is used to show the differences that exist in the group. The Ford is big so we can say “the Ford is the biggest”. Because the Toyota is small, we can say “The Toyota is the smallest”. To learn to use these we need to learn five basic rules.

Let's review Comparative and Superlatives.

Forming Comparative and Superlative Adjectives

One-syllable adjectives.

Form the comparative and superlative forms of a one-syllable adjective by adding –er for the comparative form and –est for the superlative.

One-Syllable Adjective	Comparative Form	Superlative Form

old	older than	the oldest

If the one-syllable adjective ends with an e, just add –r for the comparative form and –st for the superlative form.

If the one-syllable adjective ends with a single consonant with a vowel before it, double the consonant and add -er for the comparative form; and double the consonant and add –est for the superlative form.
