means A person who sets money aside now instead of spending it, on behalf of a future they haven't met yet.

from Straightforward lineage: 'saver' comes from 'save,' from Old French 'sauver,' from Latin 'salvare' — to make safe, to preserve from harm or loss — itself rooted in 'salvus,' meaning safe or whole. The -er simply names the one who does it. The word's oldest sense was about rescuing bodies and souls from danger; only later did it settle comfortably onto bank accounts, treating a stash of money as something being kept safe from ruin, much like a person pulled from a river.
