the.com/prune juice

means A juice pressed from dried plums, drunk less for refreshment than for its reliable effect on a sluggish digestive system.

from Straightforward compound: 'prune' comes via French prune from Latin prunum, meaning plum, while 'juice' traces back through French jus to Latin ius, meaning broth or sauce. Prunes themselves are simply dried plums — the name just carried over when the fruit got liquefied. The word's plain, unglamorous lineage matches the drink's reputation: nobody dressed this one up with marketing poetry, the fruit did all the talking.
