It is important, too, to note that writing systems are  for instance, Polish is written (today) using the Roman alphabet, but Russian, a related Slavic language, uses the Cyrillic; Yiddish, a Germanic language, is written in Hebrew characters; Latin, Greek, and Sanskrit, which resemble one another rather closely in some respects, all use different alphabets; and early examples, utterly unrecognizable to untrained readers of modern languages, were written in cuneiform, quite suitable for writing on soft clay tablets with a pointed stylus, and hieroglyphics.
