WORDS THAT USE NEPHRO-

What does nephro- mean?

Nephro- is a combining form used like a prefix meaning “kidney.” It is often used in medical terms, especially in anatomy and pathology.

Nephro- comes from the Greek nephrós, meaning “kidney, kidneys.” The Latin word for kidney is rēnēs, yielding such English words as renal.

What are variants of nephro-?

When combined with words or word elements that begin with a vowel, nephro- becomes nephr-, as in nephralgia.

Examples of nephro-

An example of a word you may have encountered that features nephro- is nephrolith, “a renal calculus; kidney stone.” (Ouch.)

Nephro-, as we’ve seen, means “kidney,” and -lith is a combining form meaning “stone.” So, a nephrolith literally translates to “kidney stone.”

What are some words that use the combining form nephro-?

What are some other forms that nephro– may be commonly confused with?
