The Semitic letter Dāleth may have developed from the logogram for a fish or a door.[2] There are many different Egyptian hieroglyphs that might have inspired this. In Semitic, Ancient Greek[3] and Latin,[4] the letter represented Script error: No such module "IPA".; in the Etruscan alphabet[5] the letter was archaic but still retained. The equivalent Greek letter is delta, Δ.[3]
The minuscule (lower-case) form of 'd' consists of a lower-story left bowl and a stem ascender. It most likely developed by gradual variations on the majuscule (capital) form 'D', and is now composed as a stem with a full lobe to the right. In handwriting, it was common to start the arc to the left of the vertical stroke, resulting in a serif at the top of the arc. This serif was extended while the rest of the letter was reduced, resulting in an angled stroke and loop. The angled stroke slowly developed into a vertical stroke.[6]
