Definition of the word kidney

The origins of the word "kidney" can be traced back to the Old English word "cyrnicign," which means "childmaker" or "childbewrapper." This is believed to refer to the shape of the kidneys, which resemble the curvature of a fetus in the womb. The term evolved over time, with Middle English texts using "kyndreien," which translates to "kidneys." In Old French, the term for kidneys was "riñon," which then likely influenced the modern English word "renal," which is derived from the Latin word "renalis," meaning "kidney." In summary, the term "kidney" has a long and fascinating history, with its origins tracing back to the shape of the organs and the language of ancient times.
