An adverb describes, modifies or provides more information about a verb in a sentence. Many adverbs in the English language end with the suffix -ly since it is a quick way to turn an adjective into an adverb - so "sad" becomes "sadly" and "perfect" becomes "perfectly."
The -ly suffix is also an excellent way to describe how something, or how often, something is done.
As many adverbs end in -ly, looking for that ending is often an easy way to identify an adverb in a sentence, but remember that not all of them do. Common adverbs that don't end in -ly include "only," "very" and "never."

Exercise a watchful eye when you're using adverbs, as people often used them incorrectly, getting them confused with adjectives. A very common error that people make is to say "I ran to the store quick" or "He runs very quick." This is not the proper usage of the word "quick."
In these sentences, "quick" is modifying "ran" and "runs." Those words are verbs, and need to be modified by an adverb, not an adjective. Therefore, the appropriate form of the word to use is "quickly."
The adjective "good" and adverb "well" are also often used interchangeably. Read our article on When to Use Good and When to Use Well to learn more about this confusing issue.
