Comparative adjectives with only one syllable are made by adding “er” to the end of the adjective

We make comparatives with one syllable adjectives ending with a vowel and consonant by doubling the consonant at the end and adding “er” at the end of the adjective.
for example: big (“i” = vowel and “g” = consonant)

* NOTE: This is not always the case, there are some exceptions.
It’s cooler today than it was yesterday.
We make comparatives with adjectives having two or more syllables by adding more before the adjecitve
For example: complicated, /com-pli-ca-ted/, has four syllables.
He thinks the sequel is more interesting.

* NOTE: We can make negative comparisions using less with these types of adjectives.
