What is the meaning of pruberty?

It seems there might be a typo in your question, as "pruberty" does not appear to be a recognized term. If you meant "puberty," it refers to the developmental stage during which a child's body matures into an adult body capable of reproduction. This period typically occurs between the ages of 9 and 14 for girls and 10 and 15 for boys, characterized by physical, hormonal, and emotional changes. If you meant something else, please clarify!
