Comparative adjectives are used to compare two things and can be either superior or inferior. The superior comparative indicates one thing surpasses another and is formed by adding "-er" to short adjectives or using "more" with long adjectives followed by "than". The inferior comparative, used to indicate one thing is less than another, is formed by adding "less" before the adjective followed by "than".
