Comparative and Superlative Adjectives

Study grammar please!

We use comparative adjectives with than to compare one person or thing with another.
Short adjectives have one or two syllables. Loud has one syllable. Pretty has two syllables. We add “er” to the adjective.
Examples: Loud-----louder     Pretty------prettier

Long adjectives don’t change the ending of the adjective. We put more before the adjective.
Examples: This book is more interesting than that book.

The opposite of more is less. We use less in the same way as more.
Ex: This book is less interesting than this book.

We use superlative adjectives to compare a person or thing with a group of other people or things.
We write “the” before the adjective and we add “est” to the adjective.
Ex: The loudest     The prettiest    The tallest    The Shortest

Long adjectives: We add “the most” before the adjective.
Example: This book is the most interesting.

The opposite of the most is the least.
Example: The least beautiful.

The best
The worst
The most
The further
The furthest
The least

Zero conditional

Zero Conditional: Certainty

We use the so-called zero conditional when the result of the condition is always true, like a scientific fact.
Take some ice. Put it in a saucepan. Heat the saucepan.
What happens? The ice melts (it becomes water). You would be surprised if it did not.

IF condition result
  present simple present simple
If you heat ice it melts.

Notice that we are thinking about a result that is always true for this condition. The result of the condition is an absolute certainty. We are not thinking about the future or the past, or even the present. We are thinking about a simple fact. We use the present simple tense to talk about the condition. We also use the present simple tense to talk about the result. The important thing about the zero conditional is that the condition always has the same result.
We can also use when instead of if, for example: When I get up late I miss my bus.
Look at some more examples in the tables below:

IF condition result
  present simple present simple
If I miss the 8 o'clock bus I am late for work.
If I am late for work my boss gets angry.
If people don't eat they get hungry.
If you heat ice does it melt?
result IF condition
present simple   present simple
I am late for work if I miss the 8 o'clock bus.
My boss gets angry if I am late for work.
People get hungry if they don't eat.
Does ice melt if you heat it?
