Pairing tips
Water word names (River, Cove, Bay) anchor best with a traditional partner — River James, Margaret Bay. Etymology picks (Dylan, Marina, Cordelia) already read as “normal names,” so they can carry a bolder middle. Watch for unintended nautical overload: Kai Fisher Marlow may be one wave too many.
