It is often written alongside the nu "pot" hieroglyph (W24). It is used as an ideogram or determinative in the context of "grains", "grinding stone", "grind", "to rub out". Budge's dictionary to the Book of the Dead has the following uses for the hieroglyph: Budge's two-volume dictionary has entries for "rub out" and "grind", both connected to Coptic language words. Of the thirty-three entries, six refer to these two definitions.
