However, it's important to note that "beggy" is not a standard English word. It is a slang term often used to describe someone who is being overly insistent or pleading for something.
If you're looking for a more formal way to express the same idea, you could use words like:
* Pleading
* Entreating
* Supplicating
* Beseeching
* Importuning
The best choice will depend on the specific context.
