Taxonomy has 4 different meanings across 1 category:
a classification of organisms into groups based on similarities of structure or origin etc
"The biologist spent years developing a new taxonomy that grouped species according to their shared structural features and evolutionary origins."
(biology) study of the general principles of scientific classification
"The professor introduced the class to taxonomy, explaining it as the biological study of the general principles used for scientific classification."
practice of classifying plants and animals according to their presumed natural relationships
"The biologist spent her career refining the taxonomy of local flora to better understand how different species are naturally related."

In plain English: Taxonomy is the science of sorting and naming living things into groups based on how they are alike.
"Scientists use taxonomy to classify plants and animals into groups based on their shared characteristics."
Usage: Taxonomy refers specifically to the scientific method of classifying organisms into hierarchical groups based on shared characteristics, rather than just listing them arbitrarily. Use this term when discussing biological organization systems like domains and kingdoms, not for general categorization in non-scientific contexts where "classification" is more appropriate.
The word comes from French and is formed by combining the Greek roots taxon (meaning a category or group) and -nomos (meaning law). It originally referred to the science of classification based on these groups.
