Adjectives in the comparative, equative or superlative form are used to compare two or more elements.

When compared elements have equal value or status, use the equative expression as … as with the invariable adjective in between. Make the sentence negative to express unequal value or status.

My new job is as stimulating as the previous one. This store is not as big as the one where I used to work.

Comparatives compare two individuals, groups or things. When the comparative form is followed by a noun or an object pronoun, it always requires than. If the second part of the comparison remains implicit, than is not needed.

Lizzie is younger than her sister. She has more varied interests than her. Both are growing taller every day. (implied: taller than before)

Superlatives express a comparison between one element that is mentioned and several others that may remain implicit. The superlative form is always preceded by the or a possessive determiner.

Ben is the kindest volunteer I have met. The Mona Lisa has the most mysterious smile. What is your biggest fear?
