a means of consulting the dead: the summoned spirit, the ritual pit or instrument used to reach it, or the medium who conducts the rite
This word belongs to the outlawed world of consulting the dead, and it slides among three connected things: the ghost that answers from below the ground, the pit or instrument used to reach it, and the human medium who runs the rite. One word could carry all three because, in the culture that produced it, they were three faces of a single practice.
The word almost never travels alone. In eleven of its appearances it is paired with the "knowing spirit" (יִדְּעֹנִי), a matched term for a specialist in hidden knowledge, and in the account of Josiah's reforms it is purged alongside household ancestor-images (תְּרָפִים). That last setting shows it could also name something physical you could burn.
Over time the center of gravity shifted. The oldest texts point to a physical installation someone could build, remove, or destroy; the prophets use the word for the thin, chirping voice of the dead itself; and the later laws use it for the forbidden specialist. This is why English Bibles reach for "medium," "familiar spirit," "ghost," or "necromancer" depending on the verse: no single English word holds the whole range.
