The phrase "be based on" is a phrasal verb commonly used to describe the fundamental or underlying principles, concepts, or ideas upon which something is derived, constructed, or organized. It signifies that a particular thing, such as an idea, theory, decision, or creation, is reliant on or supported by a specific set of principles, facts, evidence, or sources.
When something is said to be based on something else, it implies a strong connection and dependence on that particular factor. It suggests that the subject in question has been developed, formed, or built upon a solid foundation, often through careful research, analysis, or consideration of relevant information. This connection may apply to various fields or contexts, including scientific research, academic studies, creative works, business strategies, legal arguments, or personal opinions.
Furthermore, the phrase emphasizes the notion of using a principle, fact, theory, or source as a starting point or reference to establish the validity or credibility of a particular claim, argument, or statement. In this context, "be based on" can also imply that the subject is grounded in existing knowledge, experience, or expertise, and that it draws heavily from these established factors to provide a rationale or justification for its existence, purpose, or validity. Thus, "be based on" denotes the reliance on a particular foundation or starting point to substantiate and support the subject matter at hand.
