What suffix nal mean?

Answer 1

The English suffix '-nal' or '-nus' is a suffix that when combined with a latin orgin root gives the English meaning of belonging to. For example, -nal combined as suffix to the Latin root matr- [in English mother] gives maternal that means motherly or related to mother.

Answer 2

Oh, dude, the suffix "nal" is used to form adjectives that describe something as being related to or characterized by a particular noun. So, like, if you add "nal" to "professio," you get "professional," which means relating to a profession. It's like word magic, but with less wands and more grammar.
