The "-ly" suffix is typically used to create adverbs from adjectives. For example:
* slow (adjective) -> slowly (adverb)
* quick (adjective) -> quickly (adverb)
* happy (adjective) -> happily (adverb)
While there are a few words like "ugly" that look like they might be verbs ending in "-ly", they are actually adjectives. There are no verbs in the English language that follow this pattern.
