For a long time, I have been working on translating the New Testament, written in Koine Greek (a common language from the eastern Mediterranean to the Middle East during the time of Christ), into the original language. Through the translation work of this language and books, which were used in a simple manner at that time, although they were precise, I was aware of the commonality and similarity of the basic parts of the language and the peculiarity of the logic. It is very useful in teaching languages such as English and Japanese that have not been completed to that extent.
