When we talk about two things, we can "compare" them. We can see if they are the same or different. Perhaps they are the same in some ways and different in other ways. We can use comparative adjectives to describe the differences.
・Comparative adjectives are used to compare 2 nouns.
・To state that one noun has more of something then the 2nd noun.
NOTE: Superlative adjectives are used to compare 3 or more nouns.
・The black dog is older than the white dog.
・My house is bigger than my sister's house.
・The yellow hat is more expensive than the green hat.
Add -r to the end of the word.
・wide - wider
・late - later
・large - larger
・wise - wiser
Double the consonant and add -er to the end of the word.
・big - bigger
・fat - fatter
・thin - thinner
・hot - hotter
Add - er to the end of the word.
・high - higher
・old - older
Change 'y' to 'i', and add -er to the end of the word.
・happy - happier
・easy - easier
・angry - angrier
・busy - busier
・early - earlier
Place 'more' before the adjective.
・beautiful - more beautiful
・pleasant - more pleasant
・expensive - more expensive
・important - more important
・We use comparative adjectives when talking about only 2 things .
・Often, the comparative adjective is followed by "than".
・Danny is 1m95. He is tall. But Baba is 2m09. He is taller thanDanny.
・America is big. But Russia is bigger.
・He wants to have a more powerful gun.
・Is Japanese more difficult than Chinese?
Although we use comparative adjectives when talking about two things (not three or more things), in fact one or both of the things may be a group of things.
・Mt Everest is higher than all other mountains.
Here, we are talking about hundreds of mountains, but we are still comparing one thing(Mt Everest) to one other thing (all other mountains).
Also, not to use "more" along with a comparative adjective formed with -er nor to use "most" along with a superlative adjective formed with -est
Do not write that something is more heavier or most heaviest.
It is very important that we can not use "more" and "most" with -er and -est forms at same time.
You must remember this!
The "as ~ as~" construction is used to create a comparison expressing equality
・He is as foolish as he is large.
・She is as bright as her mother.
A superlative adjective expresses the extreme or highest degree of a quality. We use a superlative adjective to describe the extreme quality of one thing in a group of things.
・Superlative adjectives are used only if 3 or more things or people are being compared.
・Danny is the tallest of all the students.
・Comet is the biggest of all the dogs in the neighborhood.
・Michelle is the happiest girl in the world.
Add -st to the end of the word.

・large - largest
・wise - wisest
Double the consonant and add -est to the end of the word.
・big - biggest
・hot - hottest

・high - highest
・old - oldest
Change 'y' to 'i', and add -est to the end of the word.

Place 'the most' before the adjective.

We use a superlative adjective to describe one thing in a group of three or more things.
・The black dog is the biggest.
・The house at the end of the street is the nicest.
・My mother's pizza is the best.
When we compare one thing with itself, we do not use "the":
