The diagram illustrates five prominent writing systems from all over the world, that was divided by the structure of characters.
Overall, it is clear from the data that people form speech due to national features. Therefore I emphasized two various groups. The first one respond to more plain structure. Logographic system includes one word as a character. The great example of such structure is Chinese. Moreover several languages could use same writing system. The syllabic type divides words into syllables (Kana).
By contrast, there exists other type that involves sounds. Abjad group of languages consists of only consonant characters. In fact, historically it is the pioneering system of writing that was based on sounds. Abjuda and Alphabetic structures contain consonants and vowels. However, the first one necessarily include both of them.
In brief, historically it turned out that geographically divided cultures use absolutely different languages. They varies depending on presence of word, syllable or sounds structure.
