TONITTO

Do not compare an adverb that ends in -ly by changing the ending to -er. This error is common in speech. Instead, add more:
Wrong: Adrian runs QUICKLY. He runs QUICKER than Jacob.
Right: Adrian runs QUICKLY. He runs MORE QUICKLY than Jacob.

However, some adverbs that do not end in -ly are made into comparatives by adding -er:
Right: Adrian runs FAST. He runs FASTER than Jacob.
