The phrase "makes sense" refers to something that is logical, coherent, or understandable. When an idea, statement, or situation makes sense, it means that it follows a clear reasoning or thought process that is easy for someone to grasp. Essentially, it helps you realize that a particular concept or argument is reasonable and aligns with your understanding.
The expression "makes sense" originates from the combination of the verb "make," which comes from the Old English "macian," meaning to bring about or create, and the noun "sense," derived from the Latin "sensus," referring to perception or understanding. Together, they convey the idea of creating a perception or understanding that is logical.
