[Noun]+[Verb]+[Superlative]
Comparative adjectives
Comparative adjectives are used to compare differences between the two objects they modify (larger, smaller, faster, higher).
Noun (subject) + verb + comparative adjective + than + noun (object).
My house is larger than hers.
Superlative adjectives
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).
Noun (subject) + verb + the + superlative adjective + noun (object).
My house is the largest one in our neighborhood.
One syllable adjectives
Add -er for the comparative and -est for the superlative. If the adjective has a consonant + single vowel + consonant spelling, the final consonant must be doubled before adding the ending.
Two syllables
Adjectives with two syllables can form the comparative either by adding -er or by preceeding the adjective with more. These adjectives form the superlative either by adding -est or by preceeding the adjective with most. In many cases, both forms are used, although one usage will be more common than the other. If you are not sure whether a two-syllable adjective can take a comparative or superlative ending, play it safe and use more and most instead. For adjectives ending in y, change the y to an i before adding the ending.
Three or more syllables
Adjectives with three or more syllables form the comparative by putting more in front of the adjective, and the superlative by putting most in front.
Irregular comparatives and superlatives
These very common adjectives have completely irregular comparative and superlative forms.
