The fifth letter of the alphabet, E, is derived from a Semitic consonant that matches the English hê, Greek e, and Latin e. It's possible that the original Semitic character was derived from an earlier pictograph depicting a lattice window or a fence. Both the uncial and cursive versions were rounded starting in the 4th century CE. The Carolingian form evolved from them, and the present minuscule e is derived from it.
