GRAMMAR - Superlatives

Superlative adjectives are used in English when we want to compare three or more different things. Just like comparative adjectives, superlatives are very common in English and are an area where students make small ‘silly’ mistakes.

First you must ask yourself, ‘How many things am I comparing?‘ If you are comparing only two things then you must use a comparative (see above), if it’s three of more, then it must be a superlative.

You then need to decide if the Adjective you are using is either one syllable, two syllables ending in ‘y’, or 2 or more syllables. The forms for each type are in the image.
