An adjective is a word such as "tall", "lonely" or "educational" that either describes or gives more information about a person or thing. Adjectives usually come before nouns and after being and sensing verbs such as "taste" and "feel".

The Order of Adjectives
When using multiple adjectives together there is an order:
Quantity, Value/opinion, Size, Temperature, Age, Shape, Colour, Origin, Material

Using Adjectives to Compare
To compare the attributes of two things that are equal this is the structure to use:
as + adjective + as

To compare the attributes of two things that are unequal these are the structures to use:
not as + adjective + as
less + adjective + than
adjective + than

Adjectives Describing Quantity
When comparing things that are equal this is the structure to use:
as + adjective indicating quantity + (noun) + as
I had as many books as a library has in my house.
There were as many dogs as there were people at the party.
If I had as few problems as you do, I would be more relaxed.
When comparing things that are unequal this is the structure to use:

Comparative adjectives allow us to compare two nouns to one another. Here is the structure we use with comparative adjectives:
Noun (subject) + verb + comparative adjective + than + noun (object).
Most comparative adjectives are formed by adding "r" or "-er" to the end of the adjective or "more" in front of the adjective.
The fir tree is stronger than the pine tree.
My friend is older than your friend.
Your health is more important than your need for sweet snacks.
The green and the red sweets both taste good, but I like the green better . ("...than the red." is implied).
A superlative adjective compares three or more nouns and takes the comparison of nouns to the highest degree. Here's how to structure it:
Noun (subject) + verb + the + superlative adjective + noun (object).
Most superlative adjectives are formed by adding "-est" to the adjective or "most" in front of the adjective.
Jim's mom is the most intelligent person I know.
My town has the smallest library in the country.
Our dog is happiest when she is chewing on a bone.
