uña
/ˈuɲa/ · B1 · noun · f
fingernail
💅🐾 From Latin ungula, hoof or claw, like English ungulate (hoofed animal)
Latin unguis meant nail or claw, and ungula was a smaller form of it. Spanish dropped the g, so ungula became uña. The English words ungulate and unguent come from the same root. That is why uña can mean a fingernail, a claw or a hoof.
