2NI Comparatives and superlatives

Comparative adjectives are used to compare differences between the two objects they modify (larger, smaller, faster, higher).

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.
