Glyph origin
Representing an irrigation canal. In hieroglyphic text, this glyph developed from a variant of   in the 11th Dynasty, which in turn had partly supplanted  , its variants    and   , and    in the 8th Dynasty. However, in hieratic, a glyph much like this one was already in use since the Old Kingdom. Ultimately, the glyph  remained in use through the 18th Dynasty, when it was largely again supplanted by    as a determinative for land.

As part of a determinative for time, this glyph instead developed from , which became conflated with the irrigation-canal glyph.
