Alphabet characters were the basis for hieroglyphic writings. The basic hieroglyph characters
are refered to as the ALPHABET. They 'spell out' names or anything which can't be represented by other characters. The alphabet
characters are read as the sound of the object they represented.Although vowels were used in the spoken language.
Just like every written language, hieroglyphic writings needed conventions to keep writings consistent and readable.
For instance English is always read left to right.
