* Naive and innocent: This is the more common meaning. An ingenuous person is someone who is trusting, easily persuaded, and lacks experience. They might be considered gullible or even foolish.
* Clever and inventive: This meaning is less common but still valid. An ingenuous person can also be someone who is resourceful, creative, and able to come up with clever solutions.
So, is an ingenuous person naive or crafty?
It depends on the context. If the focus is on their innocence and lack of experience, then they are naive. If the focus is on their resourcefulness and inventiveness, then they are crafty.
Here are some examples:
* Naive: "The ingenuous young woman believed everything the salesman told her."
* Crafty: "The engineer's ingenious invention solved the problem in a completely unexpected way."
It's important to pay attention to the specific context to determine which meaning of "ingenuous" is intended.
