Etymology

Origin of enclosure

First recorded in 1450–1500; enclose + -ure


Explanation

An enclosure is something that closes you in, like a pen or a cage. When a cobra disappeared from an enclosure at the Bronx Zoo, the entire Reptile House had to be shut down until the snake was found. An enclosure can also be something that's included in an envelope with a cover letter of some sort. If you're sending a letter to your literary agent and you’re including a few pages of your latest limericks, you might put "enc." at the bottom of the letter, to indicate that you've included something extra in the envelope — an enclosure.
