Etymology
Origin of separation
1375–1425; late Middle English < Latin sēparātiōn- (stem of sēparātiō ), equivalent to sēparāt ( us ) separate + -iōn- -ion
Explanation
When two things that were together come apart, it's a separation, whether they're the two halves of your Oreo or a married couple splitting up. If you leave your beloved cat to go to college, it's a separation — the two of you are parting ways, at least for a little while. The root is the Latin word separare, which means "to pull apart." A separation from someone you care about can be hard, but the trickiest thing about separation is remembering how to spell it. One common trick is to keep in mind that there's "a rat" in the middle of the word.
