Etymology

Origin of unlisted

First recorded in 1635–45; un- ¹ + list ¹ + -ed ²

Explanation

Something that's unlisted hasn't been recorded or registered, often because it's private. If you have an unlisted phone number, it doesn't show up in the phone book or in online searches. You might keep careful notes on all the books you've read, but there are still bound to be some that are unlisted, not featured on any of those lists you've compiled. And any collectables your grandpa hasn't yet added to his online shop are also unlisted. This adjective is great for describing anything not included on a list, from a company's privately traded stocks to an unregistered voter's name.
