What does sarco- mean?

Sarco- is a combining form used like a prefix meaning “flesh.” It is often used in medicine and biology.

Examples of sarco-

One word you may be familiar with that features sarco- is sarcophagus, “a stone coffin, especially one bearing sculpture, inscriptions, etc., often displayed as a monument,” especially in ancient Egypt, Greece, and Rome. The word sarcophagus—not to be confused with the related word sacrophagous—comes from a Greek word meaning “flesh-consuming”; the Greeks believed there was a kind of stone thought to consume the flesh of corpses, and so it was used for coffins.

Another term using sarco- that you may have heard is sarcomere, an anatomical term for a part of certain types of muscle. Now, we know sarco- means “flesh.” The second part of the word, -mere, comes from the Greek méros, meaning “part.” Sarcomere literally translates to “part of flesh.” Fortunately, the word sarcomere is far more specific than its literal meaning would suggest!

Sarco- also appears in sarcosuchus, the name of an extinct relative of the crocodile that clocked in at over 30 feet long and nearly 10,000 pounds. This formidable “super-croc,” whose name literally means “flesh crocodile,” lived over 100 million years ago in what is now Africa and South America. The sarcosuchus notably figures in the 2017 video game Ark: Survival Evolved, where the giant reptile is popularly called Sarco for short.
