A fun word because, while old, nobody has a clue where it comes from.
Roam (v) - to wander about without purpose. Dates back to at least the 14th century. Many etymologists believes it is comes from the city of Rome, that English pilgrims had to take a circuitous route around France getting to the holy city. There is no actual evidence for this theory, though. There is a similar word in Old English (ramian) which may have come from a Saxon or Dutch word. The experts are puzzled by this little word.
Roam is also something that Buffalo used to do in the old West. Art is by Tate Hamilton.
