The ancient Egyptian Bread bun hieroglyph is Gardiner sign listed no. X1 for the side view of a bread bun. It is also the simple shape of a semicircle. The hieroglyph is listed under the Gardiner category of loaves and cakes.
The bread bun hieroglyph is used in the Ancient Egyptian language hieroglyphs for the alphabetic consonant letter t. A later alternative t, is a pestle, with curved top, Gardiner U33. U33
"Bread bun/semi-circle" as feminine determiner
Besides alphabetic-t, the bread bun is used for words that are feminine, as an end qualifying determinant, often shown before other qualifying ideograms or determinants in the hieroglyphic word block-(quadrat hieroglyphic block). It is one of the most frequently used signs in hieroglyphic writing.
Palermo Stone
The t hieroglyph is used extensively throughout the Palermo Stone of the 24th to 23rd century BC, and it is used in the first row (Row I of VI), for the naming of King Tiu of Lower Egypt (a King of the North).
