[Music] when we use adverbs in sentences which describe verbs we often times add an ly uh to an adjective to make it an adverb for example take a look at the sentence the quick brown fox jumps over the lazy dog in this case we have the word quick which is functioning as an adjective because it is describing the fox adjectives describe nouns and so we don't need to add an ly to the end of this word because it's working as an adjective in the sentence but there are times that we do need to add an L take a look at this sentence the fox jumped quickly in this case the word quick is being used to describe how the fox jumped and so it's an adverb it's describing a verb and we add ly to the end of the word quick to make it an adverb one thing to note is that some adverbs don't work this way for example if we say the fox ran fast in this case the word fast is an adverb it's described describing the way that the fox ran but we don't add an ly to it so often times in grammar there are exceptions to the rule which is why if you're unsure it's good to look it up but as a general rule of thumb it's good to add ly to an adjective to turn it into an adverb [Music]
