Did You Know?

We bet you thought "intestine" was a noun referring to a part of the digestive system! It is, of course, but naming that internal body part isn't the word's only function. Both the noun and the adjective "intestine" have been a part of English since the 15th century, and both trace to the Latin adjective intestinus, meaning "internal," and ultimately to intus, meaning "within." Though the adjective "intestine" turns up much less frequently than does its anatomical cousin, it does see occasional use, especially as a synonym for "civil" and "domestic" (in contrast to "foreign") applied to wars and disturbances.
