What does ingenious mean?
Ingenious describes a person, idea, solution, or device that displays unusual creativity, cleverness, and resourcefulness. It often implies more than simple intelligence: the person has found an original and effective way to solve a problem, make something, or use limited resources. The adjective is especially appropriate for ingenious inventions, ingenious methods, and ingenious solutions, and it normally conveys admiration. In modern English its dominant sense concerns invention and cleverness, though the word historically had connotations of frankness or noble birth. Ingenious should not be confused with ingenuous, which means innocent, candid, and free of guile. Because ingenious emphasizes both originality and practical effectiveness, it is stronger than a general word such as clever. It can describe human ingenuity, a plan, a piece of technology, or an artistic construction. The word is useful when praising an idea that is not only workable but elegant or unexpected.

Ingenious and ingenuous look almost identical, but one solves problems creatively while the other simply tells the truth.

The adjective comes from Latin ingeniosus, meaning “clever, inventive,” which was formed from ingenium, “natural talent, cleverness, or inventive ability.” English borrowed the word in the early 17th century. Its relatives include genius, engineer, and engine, while ingenuous comes from a related Latin word meaning “frank” or “freeborn” and now usually denotes innocent honesty.
