Definition: Arpen refers to a person who speaks or writes in a foreign language, often an unknown language. It comes from the Greek word "arpeanoi" which means "speakers" or "learned." In this context, it might mean someone who has studied and knows the language well enough to be able to communicate in it. The word is used metaphorically in scripture when describing those who speak foreign languages or have advanced knowledge of a culture's language, making them "arpen".
