WRITING AND UNDERSTANDING

In whatever language people writes in, people must understand hence people learn other peoples' language: language is no longer barrier, worst, one can get interpreter.

Whatever thing you scratch on a pad forms a writing, and then any style or shape calls for one to understand. Writing and understanding calls for a special skill hence you see people studying linguistic.
