subclass
Category within category
A subclass is a category that falls within a larger class, sharing its general characteristics while having additional distinguishing features.
In biology, it's a taxonomic rank between class and order.
In object-oriented programming, a subclass inherits properties and methods from a parent class while adding or modifying its own: The Button subclass extends the Widget class.
