As in Spanish, English, when comparing two things we want to use adjectives and their varying degrees: positive, comparative and superlative.
- The good referred to the degree simplest form:
A sunny day
- The comparison refers to a degree higher quality of one thing over another.
A better day
- The degree superlative quality concerns in its highest expression:
Today is the best day of the year
COMPARISON OF CLASSES

- COMPARISON OF EQUALITY

With the adjective form is interspersed between the "ace ace ..." (as tan. ..) for phrases and affirmative interrogatives and "not as ... as" or "not so ... as" negative for the phrases .
I'm as young as you
I am as young as you?
I'm not so young as you
We can use after the second 'he' pronoun in the nominative and accusative case (He, his; She, her ...)
He is as young as she; He is as young as her
If this is a comparison between two verbs, we can use the phrase "as much as (much as) in a negative way
She does not work as much as she should
When the comparison is made between two nouns have used "as much as" to the singular and "as many as" for the plural.
I have as much work as my boss
I have as many pencils as you
If we are comparing two substantive accounting (books, cars, houses ...) use "as many as ..." but if we are comparing two substantive uncountable (wood, weather, music ...) we will use the building "as much. .. ace. "
We have as many books as them
We have as much space as them

- COMPARISON OF LOWER

With the adjective form is interspersed among the "less than ..." (menos. that ..) but it is more usual to find the comparison of equality in a negative way (which has the same meaning).

He's less than you young

He's not as young as you

Normally it is used less for fewer and for accounting uncounted

- COMPARATIVE Superior

It is formed of two ways:

Adding the adjective suffix-er for the comparative superiority and-est for the superlative..

=	+ er	+ est
big (grande)	bigger (más grande)	biggest (el más grande)

The word more precedence (over) for the comparative superiority and "the most" for the superlative

intelligent

more intelligent

the most intelligent

The one-syllable adjectives form the comparative and superlative with-er and-est

old, older, the oldest

new, newer, the newest

dark, darker, the Darkest

The two syllables ending in er, and he and ow and those with the accent (prosodic) on the last syllable also form the comparative and superlative with-er and-est

clever, cleverer, the cleverest

idle, Idler, the idlest

happy, happier, the happiest

narrow, narrower, the narrowest

The remaining two-syllable adjectives and all of three or more form the comparative and superlative with more with most.

interesting, more interesting, the most interesting

COMPARATIVE AND SuperLan IRREGULAR

Some adjectives are the comparative erratically

good, better, the best

bad, worse, the worst

far, further, the furthest

CONSIDERATIONS
