What language is salve?

"Salve" is a Latin word meaning "be well" or "hello." It's often used as a formal greeting in Latin texts and has been adopted into other languages as well.

However, if you're thinking of a "salve" as a type of ointment, then the language would be English. This usage comes from the Latin word "salve," but the English version has evolved to become a common noun for a healing balm.
