How many different type of scripts are there in the world?

Answer 1

There are at least 6000 languages currently spoken, but not all of them have a writing system and some of them use modified forms of existing writing systems. As for types, there are alphabets (e.g. English, Georgian, Cyrillic), syllabaries (e.g. Japanese kana, Native American languages such as Ojibwe and Cree, Yi), syllabic alphabets (e.g. Bengali, Hmong, Thai), abjads (e.g. Arabic, Hebrew), and semanto-phonetic scripts (e.g. Chinese, Japanese kanji, Egyptian hieroglyphs). There may be other, still unknown types hidden in undeciphered scripts, but for now these five are clearly identified.

Answer 2

There are numerous types of scripts used around the world, including alphabets, abjads, abugidas, and syllabaries. Each script type has its own unique characteristics and is used by different languages to represent their sounds. It's difficult to provide an exact number as new scripts may still be in use or have been developed.
