why dehydrated grapes and plums are called raisins and prunes, respectively, but we don’t name other dehydrated fruits different from their original names?

Question

Where did the naming convention come from for these two fruits and why isn’t it applied to others?

Edit: this simple question has garnered far more attention than I thought it would. The bottom line is some English royals and French peasants used their own words for the same thing but used their respective versions for the crop vs the product. Very interesting. Also, I learned other languages have similar occurrences that don’t translate into English. Very cool.

Another question is why there is prune juice. Like, how do you get juice from a dried fruit?

Turns out it’s more like prune tea. You dehydrate the plums to make prunes, and then you add water to the prunes and let them steep, and then you remove the water which is now prune juice. So, remove water, add water, remove water again. And prune “juice” is different from plum juice.

Interesting.

No, wait. The other one.

Tedious.
