Theory
A theory is in general any hypothesis or set of ideas about something, formed in any number of ways through any sort of reasoning for any sort of reason. When applied to intellectual or academic situations, it is considered a systematic and rational form of abstract thinking about a phenomenon, or the conclusions derived from such thinking. It involves contemplative and logical reasoning, often supported by processes such as observation, experimentation, and research.
