Correct spelling for the English word "NOSVE" is [nˈɒsv], [nˈɒsv], [n_ˈɒ_s_v] (IPA phonetic alphabet).
I apologize, but I couldn't find any specific or widely recognized definition for the term "NOSVE." It seems to be an ambiguous term that may not be included in standard dictionaries. However, it is worth noting that there is a possibility that "NOSVE" is a made-up or unique term specific to a certain context, community, or field. In such cases, the definition may be limited to that particular context or group.
Without any additional information or context, it is difficult to provide an accurate definition for "NOSVE." If you can provide more details about the term, its origin, or the context in which it is being used, I would be happy to assist you in finding a more specific definition or explanation.
