Is there a particular word for nouns (or other words, I guess) that used to be self-descriptive but have since evolved? For instance, the word "blueprint" was coined because the diagrams were made through cyanotype process and were indeed blue prints. Now, they're made on a computer and as far as I know are no longer blue.

I can't imagine there's NOT a word for this, but I haven't been able to come up with the right combination of terms for google to spit it out. Thanks!
