What are Superlative Adjectives?
Superlative adjectives are used to describe a person, thing, or idea that has the highest or lowest degree of a quality among a group. For example, 'tallest', 'most intelligent', or 'worst'. They compare three or more items.
Superlative adjectives show the extreme degree of a quality in a group. Form: short adjectives add -est (tall → tallest); long adjectives add 'most' (beautiful → most beautiful). Always use 'the' before a superlative.
- •tall → the tallest
- •fast → the fastest
- •big → the biggest (double last letter)
- •beautiful → the most beautiful
- •intelligent → the most intelligent
- •expensive → the most expensive
