What does the suffix "-ly" generally denote?

The suffix "-ly" is commonly used to transform adjectives into adverbs, indicating the manner in which an action is performed. For example, if you take the adjective "quick" and add the suffix "-ly," it becomes "quickly," which describes how something is done. This transformation showcases that the action is being performed in a particular way, thus denoting a manner of action.

In contrast, the other options identify different functions of suffixes or parts of speech. A state of being, physical traits, and possession of attributes are not represented by the "-ly" suffix, which is specifically focused on modifying verbs to explain how actions are carried out.
