The Chinese word "俄亥俄州" is formed primarily through phonetic transliteration, where the characters "俄亥俄" are chosen to approximate the sound of the English name "Ohio", with "俄" representing the "O" sound, "亥" for the "hi" sound, and the final "俄" for the concluding "o" sound; the character "州" is then appended to indicate that it is a state, providing a semantic designation common in Chinese translations for U.S. states.
