Bread bun (hieroglyph)
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 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.
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.
It is not a bread bun hieroglyph, as Gardiner stated. The Sanskrit based glyph is tu-ng rqUx, which means 'Vaulted, high, elevated, tall, lofty, prominent, long, chief, strong, passionate, a mountain'. Sanskrit based Egyptian hieroglyph's first consonant t with vowel 'u' = "tu" rq was mostly used after the first word of a sentence (never used in the beginning of a sentence), which means '1 An adversative particle 'but, on the contrary, on the other hand, nevertheless' 2 and now, on one's part, and 3 as to, as regards, as for 4 it sometimes marks a difference 5 sometimes it is used as an emphatic particle, a mere expletive.
European English word 'to' none is but transformation of Sanskrit tu.
