An devious person or plan often means someone or something that's sneaky and cleverly tries to get what they want.
The word "devious" can have different shades of meaning depending on how it's used. When describing a path, like a road or trail, being devious just means the route is winding or indirect – not necessarily bad! You might take a devious shortcut through the woods to save time. On the other hand, when talking about people, being devious usually implies that someone is trying to be tricky or dishonest in some way. For example, if you think your friend is being devious by hiding their true intentions, it means they're not being straightforward or honest with you.
Cunning or deceiving, not straightforward or honest, not frank.
