~Families of Writing Systems~ Another way to classify writing systems is by "family". This classification can get a bit fuzzy. "Family" can denote a group of writing systems that either have evolved from a common ancestor or have similar "style" or appearance. An example of this latter definition would be Old Persian, which looks like cuneiform but isn't directly descended from Summerian or Akkadian.
Language: In this image you can see all of the Farsi letters and all 4 of their forms.There are 32 letters in the Farsi alphabet, but unlike our alphabet each letter is written differently depending on where it is in a sentence.This means if you were to learn to write in Farsi, you would have to memorize 32 letters x 4 forms to know how to write Farsi and that would equal 128 different characters to memorize!
