What does unguis mean?
Unguis is a rare noun in modern English for a claw, hoof, or nail, particularly a keratin-bearing structure at the end of an animal's digit. The word is most useful in formal zoological, anatomical, and comparative contexts, where its broad Latin-derived sense can distinguish a discrete terminal structure from the general words “claw” and “hoof.” Although dictionaries list the singular form, “ungues” is usually the form encountered in descriptions of animals, skeletons, and claws. Unguis also has etymological interest: it comes from Latin unguis, meaning “nail, claw, or hoof,” and belongs to a wider family that includes “ungual” and “unguiculate.” The word is therefore more than a technical label: it connects a precise zoological concept with a network of related terms about nails, claws, and hooves while preserving the vocabulary of classical natural history.

Where does unguis come from?
Unguis is a Latin loanword that retains the spelling and core meaning of Latin unguis, “nail, claw, or hoof.” The same Latin root underlies related English forms such as “ungual” and “unguiculate,” while “ungulate” developed through the related Latin noun ungula, meaning “hoof.” These words preserve a shared classical vocabulary for terminal digit structures and the animals characterized by them.
