Here are some examples of adverbs formed with "ly":
* Quickly: (modifies the verb "run")
* Happily: (modifies the adjective "excited")

Exceptions:
While "ly" is the most common ending for adverbs, there are some exceptions:
* Some adverbs do not end in "ly": e.g., "well," "fast," "very."
* Some words ending in "ly" are not adverbs: e.g., "holy," "ugly," "family."
It's important to consider the context of a word to determine its part of speech.
