For example, when explaining etymology of a certain word, Jaunius often searched for equivalents in the trendy Greek or Armenian languages instead of closer neighbors. He often grouped semantically similar but phonetically different words and attempted to find their true original form. While the conclusions are often incorrect, the notes are still valuable for their observational data.
Jaunius's method involved exploring word origins by comparing them to languages like Greek or Armenian that were not necessarily geographically close. He grouped words with similar meanings but different sounds and sought their true root form. The value of his notes lies in the insights they provide, even if some conclusions are incorrect.
