puberty

This term describes the biological transition from childhood to adulthood, characterized by hormonal shifts and physical development. It carries a clinical yet universal connotation, often associated with the psychological turbulence and social adjustments of adolescence. As an uncountable noun, it refers to a developmental state or process rather than a discrete object. It does not take a plural form and is typically used with the definite article or as a standalone concept in medical and psychological contexts.
