Is there a name for "definitional drift," meaning a word we've used to define something in the past, but the object of definition has changed over time, yet we keep using the same word?
For example, "phone." Back in the 80s, we had phones that were connected to walls with cords. Phones were...well, phones.
Now, we call the device we carry a "phone," even though it's barely a phone. It's primarily designed to a million things other than make phone calls, and if we list the things we do it by frequency, making or taking a phone call would likely be near the bottom of the list.
This is clearly a thing that happens. Is there a name for it? Can you think of other classic examples of it?
Edit: another example is when we record video on our phone (ha!), we often say we "taped it," or we "have it on tape." But magnetic tape has nothing to do with it anymore.
