Here's how it's used:
* "Happyly": means "really happy" or "very happy"
* "Badly": means "really bad" or "very bad"
* "Tiredly": means "really tired" or "very tired"
Examples:
* "I'm so tiredly."
* "That movie was so badly."
* "I'm happyly for you!"
Note:
* It's generally considered informal language and may not be appropriate for formal settings.
* The use of "ly" can sometimes sound childish or exaggerated.
