Usage

What does whatsit mean? Whatsit is a very informal word for an object whose name you don’t know, have forgotten, or can’t recall at the moment. It’s often used to refer to gadgets or parts of things that might not even have a commonly known name, as in Before we attach the bracket, we have to insert this whatsit here. The word is also sometimes used to refer to things that are not physical objects, such as events, types of media, or abstract concepts. It’s not commonly used to refer to people (terms used for this purpose include what’s-her-name, what’s-his-name, and what’s-their-name). There are several other similarly informal words that are used in the same way, including the very similar term whatsis as well as whachamacallit, what-do-you-call-it, thingamajig, thingamabob, thingy, doohickey, and doodad. Example: My kids got me one of those whatsits that track your steps. What’s it called? A stepometer?
