Rōnin

The word rōnin is usually translated to 'drifter' or 'wanderer'; however, per kanji, rō (浪) means "wave" (as in body of water) or "unrestrained", while nin (人) means "man" or "person". It is an idiomatic expression for 'vagrant' or 'wandering man', someone who finds the way without belonging to one place.
