A smaller group within a larger category, often used in classification systems, especially in biology.
In biology, mammals are a subclass of animals that have fur or hair and produce milk for their young.
Subclass → It is formed from "sub-" (meaning under or below) and "class" (from Latin "classis", meaning a group or category). The word "subclass" refers to a category that is under or a subdivision of a larger class.
Think of something that is a smaller category 'under' ('sub-') a larger group ('class'). This helps you remember that a subclass is a division within a broader category.
