Etymology

Origin of external

First recorded in 1375–1425; late Middle English; equivalent to extern + -al 1

Explanation

If, as a kid, you didn’t get what you wanted on your birthday, you were probably told that external, or outward, things can’t bring happiness. (It’s a noble idea, but it’s still up for debate, at least in some circles.) External contains the prefix ex- meaning “out of.” It shares this prefix with a number of other words including extraterrestrial (meaning “outside of Earth’s limits") and exclude (meaning “keep someone out”). The opposite of external is internal; again, as you’ve probably been told, it’s the internal things that really matter. What we’re wondering is: Does that include the leather interior in our dream convertible?
