"Metovum" is not a commonly used word in English, and it is unclear as to whether it is a real word or a made-up one. However, if we were to take it at face value, the word would likely be pronounced as "meh-toh-vuhm" using IPA phonetic transcription. This is based on the assumption that "o" is pronounced as "oh" and "u" is pronounced as "uh." It should be noted that without proper context or an understanding of the word's intended use, it is difficult to accurately determine its pronunciation.
