How many written languages are there?
It is widely known the fact that a written language is the representation of a language by means of a writing system.

Specialists consider that there are approximately 4000 written languages in the world. Anyway, some languages are extremely similar. For example, Serbian and Croatian are similar languages. Almost 98% of the languages have a written system.
