taxon
Noun: A taxon is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. It is a formally recognized category in biological classification, such as a species, genus, family, or order, representing a group of organisms with shared natural relationships and characteristics.
The word "taxon" is used in scientific contexts, particularly in biology and taxonomy, to refer to any named group of organisms at any level of a classification hierarchy. It is a singular noun; its plural form is "taxa."
- The species (lion) is a taxon.
- Biologists debated whether the newly discovered population constituted a new taxon.
- The family Felidae, which includes all cats, is a higher-ranking taxon than the genus .
- Monophyletic taxon: A taxon that includes a common ancestor and all of its descendants.
- Mammals are considered a monophyletic taxon.
- Type specimen: A single physical specimen (or illustration) designated as the name-bearing representative of a taxon.
- The taxon was formally described based on a type specimen stored in the museum.
- Taxa (n): The plural form of taxon.

- Taxonomic (adj): Relating to taxonomy or the classification of organisms.
- The taxonomic status of the organism is unclear.
- Taxonomy (n): The science of classification, especially of organisms.
- Modern taxonomy relies heavily on genetic analysis.
- Classification group
- Biological category
- Systematic unit
The core meaning of "taxon" is a formally defined group in a biological classification system. It is an abstract, conceptual category used for organizing and communicating about the diversity of life. The reference to "natural relations" in some definitions emphasizes that modern taxonomy aims to group organisms based on evolutionary relationships (phylogeny), not just superficial similarities.
- animal or plant group having natural relations
