Frequently asked questions

What is the difference between ingenuous and ingenious?

Is disingenuous the opposite of ingenuous?

Yes, and it is now far more common than the positive form. Disingenuous means pretending to be sincere or naive while actually knowing better, so it is not simply the absence of ingenuousness but a deliberate performance of it.

Is calling someone ingenuous a compliment?

It depends on the sense. Praising someone's ingenuous honesty is warm; calling them ingenuous about a business deal implies they were easily taken in.

What is the meaning of ingenuous?

"ingenuous" (adjective) means innocent and trusting to the point of seeming naive, particularly about people's motives.
