One way to describe nouns (people, objects, animals, etc.) is by comparing them to something else. When comparing two things, you’re likely to use adjectives like smaller, bigger, taller, more interesting, and less expensive. Notice the ‑er ending, and the words more and less. A mistake that both native speakers and non-native speakers make is using incorrectly formed comparative adjectives
Examples:
His cat is more large than my dog.
His cat is larger than my dog.
Here you have the rules how to transform the adjective into comparative adjectives.
For adjectives that are just one syllable, add -er to the end
For two-syllable adjectives not ending in -y and for all three-or-more-syllable adjectives, use the form “more + adjective.”
For two-syllable adjectives ending in -y, change the -y to -i and add -er.

Here you have some examples of comparative adjectives
Stella is a smaller dog than Bruno so she usually loses the fight over dog treats. (Stella is compared to Bruno.)
We ordered a bigger cake than usual in case unexpected guests came to the party. (The present cake is compared to the cake they usually order.)
Trey is more handsome than any movie star I’ve ever seen. (Trey is compared to a movie star.)
Susan is a kind person but she is less compassionate than Linda. (Susan is compared to Linda.)
The spring garden was lovelier than the fall display of flowers.
Today feels cooler than yesterday’s sweltering temperature.

Slide 5
We do not have to forget that exist irregular adjetives that has no rules. We just have to memorize them
Example:
Irregular Forms
Some adjectives have irregular forms in the comparative degree, meaning they don’t have a suffix –er nor do they need the words more or less. The comparative forms of these adjectives are totally different words.
good – better little – less
bad – worse far – farther
much – more
