Besides geocaching, one of my other passions is language. Although humans have used verbal language for tens of thousands of years, the invention of written language about 5,000 years ago is considered one of mankind's greatest achievements. In fact, the presence of written sources denotes the technical dividing line between what scholars classify as prehistory versus what they call history.
For this cache, you must identify various types of written languages, and connect them with the countries where they're most commonly used.
The sample texts will have the name of the language written in the script used in that language. For example, "English" is the name of the language written in English, just as 中文 is the name of Chinese written in Chinese.
