Adjectives: Comparative and Superlative

You should use the comparative form of an adjective to compare exactly two things. You can form the comparative by adding the suffix "-er" to the modifier(for some short words) or by using the word "more" with the modifier:
Now that it is March, the days are getting longer. (longer now than before)
You should use the superlative form to compare threeor more things. You can form the superlative by adding the suffix "-est" to the modifier orby using the word "most" with the modifier:
This is definitely the most beautiful and cheapest car I haveever seen
To form the comparative and superlative forms of adjectives we must take into account the number of syllables it has.
The general rules to form the comparative and the superlative ofadjectives are as follows:
1. One-syllable adjectives
- Most one-syllable adjectives add suffix –er to form the comparative and –est to form the superlative:
tall – taller – tallest
cheap – cheaper –cheapest
- Adjectives ending in –e only add –r to form the comparative and –st to form the superlative.
nice – nicer – nicest
late – later - latest
- Adjectives ending in a vowel + a consonant,double the consonant:
big – bigger – biggest
thin – thinner – thinnest
Note: real, right, and wrong always have more and most.
2. Two-syllable adjectives
2.1- Adjectives ending in consonant + -y have–ier and –iest:
pretty – prettier – prettiest
easy – easier – easiest
- Adjectives ending in –ow, –er, and –le normally take –er and –est, although more and most are also possible:
narrow –narrower – narrowest
clever – cleverer – cleverest
noble – nobler – noblest
2.2- The rest use more and most to form the comparative and the superlative, respectively.
surprised – more surprised – mostsurprised
frightful – more frightful – most frightful
However, many two-syllable adjectives may have both forms:
polite – politer/more polite – politest/most polite
common – commoner/more common...
