ingenious

Ingenious is a positive adjective used to describe clever, original, and inventive solutions, devices, or ideas. It signals admiration for resourcefulness and the ability to design or discover effective, imaginative ways to solve problems.

Origin and related terms: Ingenious derives from Old French ingenieux, via Latin ingeniōsus, from ingēnus meaning inborn or innate talent. The related noun is ingenuity. The word ingenuous, often confused with ingenious, has a different origin from Latin ingenuus meaning noble or candid, and means frank or sincere rather than clever.

Usage: The term is commonly applied in science, engineering, technology, and the arts to describe mechanisms, methods, or arguments that are notably clever and practical. It may function as evaluative praise or as a neutral description of design quality.

Nuance: An ingenious solution typically emphasizes both creativity and functionality, sometimes incorporating elegance or simplicity. It does not require high cost or notoriety, but rather effective problem solving and novel thinking. Instances range from a compact widget design to an efficient algorithm.
