The word "monu" is not a commonly used word in English, and is not found in any standard dictionaries. However, if we were to use IPA phonetic transcription to explain how this word might be spelled, it might look something like this: /ˈmɒnjuː/. The 'o' sound would be pronounced as in the word "hot," while the 'u' sound would be pronounced as in the word "to." Ultimately, without context or further information, it is difficult to determine the spelling or meaning of the word "monu."
