Invention is the process of combining existing cultural items, ideas, or technologies into a new form that did not previously exist. It involves creativity and innovation to produce something novel, whether it is a tangible object, a new method, or a new concept. Inventions can range from simple tools to complex technological systems and can have significant impacts on society and culture, leading to social change and the development of new ways of life. Invention is one of the primary drivers of cultural innovation, alongside discovery, which involves becoming aware of something that already exists but was previously unknown. The spread and adoption of inventions within a culture or across societies is a process known as diffusion.
