What does separator mean?
A separator is anything that creates a boundary between people, objects, groups, or units of information. It may be a physical object, such as a rail on a shelf, a partition between offices, or a line dividing a printed page. In computing, a separator is a character or symbol—such as a comma or tab—that marks a division between fields, records, or other elements. The word is therefore both practical and metaphorically suggestive: it names the tool or agent that keeps things apart and makes distinctions clear. “Separator” is more technical and specific than the general verb “separate,” while “divider” often emphasizes a physical partition and “delimiter” usually refers to a textual or computational marker. The noun is usually neutral and can describe anything deliberately used to distinguish one section from another, although context determines whether the separation is spatial, visual, or digital.

Where does separator come from?
Separator comes through French from Latin sēparātor, an agent noun meaning “one who or that which separates.” It ultimately rests on Latin sēparāre, “to set apart,” formed from se- (“apart”) and parare (“prepare, set up”). English “separate,” “separable,” and “separation” belong to the same Latin family.
How separator is actually used
The noun is neutral but commonly occurs in technical, administrative, and everyday contexts. It tends to describe a deliberate boundary or dividing element rather than an accidental gap or separation.
