Like A, the letter B can be traced back to ancient Phoenicia. The appearance of the letter B may be due to the symbol of a house. Like the hieroglyphics in ancient Egypt, it appeared in Semitic characters very early, about 1500 BC in Sinai Peninsula. Now it is the second letter in English.

Introduction:

C c: The letter C is called gimel in Phoenician, which stands for camel. Its arrangement in the alphabet is the same as that of the Greek letter γ (gamma). In fact, its glyph evolved from the latter. C stands for 100 in Roman numerals.

D is a hieroglyph, which depicts the shape of an ancient arch or door. In ancient Phoenician and Hebrew, it is called daleth, which means "gate" and is equivalent to the Greek letter δ (delta).
