means The act of helping, serving, or attending to others — whether as work, duty, or assistance — and also the systems and organizations set up to provide it.

from From Latin servitium, 'slavery, servitude,' built on servus, 'slave.' It traveled through Old French servise into English, where the harsh edge of bondage softened over centuries into the gentler ideas of helping, attending, and serving — though the word still carries that old thread of one person devoting effort to another's needs.
