Frequently Asked Questions
No, because the valid scientific name for the cougar/puma is *Puma concolor*. The repeating of a trade name (e.g., a brand) is not a scientific tautonym.
Yes. For example, the Eurasian wildcat is *Felis silvestris silvestris*, where the subspecies repeats the species name. This is sometimes called a trinomial tautonym.
No, the International Code of Nomenclature of Prokaryotes (ICNP) does not allow tautonyms. A name like *Helicobacter helicobacter* would be invalid.
This is an extended, informal use where an initialism repeats a letter, like 'PDF format' (where 'F' already stands for 'Format'), creating a kind of tautonym in everyday language.
