Taxonomy is the science of classifying and naming living things into groups like species, genus, and family. More generally, it can mean any organized system for grouping similar items or ideas.
It comes from Greek 'taxis' meaning 'arrangement' and 'nomia' from 'nomos' meaning 'law or method'. It originally referred to the orderly arrangement of plants and animals.
Taxonomy is like the giant filing system for life on Earth, deciding what goes in which folder and why. Once you understand how taxonomies are built, you start seeing them everywhere—from library shelves to website menus to how your brain sorts memories.
