We use comparatives and superlatives to say how people or things are different. We use a comparative adjective to express how two people or things are different, and we use a superlative adjective to show how one person or thing is different to all the others of its kind. For example, Mick is taller than Jack.
When should superlatives be used?
Superlative adjectives are used to describe an object which is at the upper or lower limit of a quality (the tallest, the smallest, the fastest, the highest). They are used in sentences where a subject is compared to a group of objects.
How do you identify comparative and superlative?
When the adjective has two or more syllables, the comparative is formed by using the adverbs 'more' or 'less', and the superlative is formed by using the adverbs 'most' or 'least'.
