The correct spelling of "wert level" is actually "vert level." The letter "w" is often used as a substitute for the letter "v" in older English texts. This word is pronounced /vɜːt ˈlɛvəl/ which means a vertical or upright position. The IPA phonetic transcription helps to accurately represent the pronunciation of words, especially when the spelling is irregular or different from what we expect. It is important to use correct spelling and pronunciation in effective communication.
