Comparative and Superlative Adjectives

The correct use of the comparative and superlative forms is a key ingredient when students are learning how to express their opinion or make comparative judgments. The following lesson focuses on first building understanding of the structure - and of the similarity between the two forms.

We use the comparative and superlative form to compare and contrast different objects in English. Use the comparative form to show the difference between two objects. Example: New York is more exciting than Seattle. Use the superlative form when speaking about three or more objects to show which object is 'the most' of something. Example: New York is the most exciting city in the USA.

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.

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