Many adverbs can have different degrees.

| Positive | Comparative | Superlative |
| quickly | more quickly | most quickly |
You've just used the comparative and superlative forms of adverbs to show different degrees.
Use the comparative form when you are comparing two actions or qualities.
Most comparative adverbs end in -er or begin with more (harder, more easily...). But, there are irregular comparatives which do not end in -er (better, worse...).
Use the superlative form when you are comparing three or more things.
Most superlative adverbs end in -est or begin with most. (hardest, most easily...). But, just like comparative adverbs, there are some irregularities (best, worst...).
| Positive | Comparative | Superlative |
| hard | harder | hardest |
| brightly | more brightly | most brightly |
| quietly | more quietly | most quietly |
| Positive | Comparative | Superlative |
| well | better | best |
| much | more | most |
| badly | worse | worst |
