Pronunciation: [wˈɛðə nˈə͡ʊ] (IPA) 
The phrase "whether no" is spelled as /ˈwɛðə noʊ/. The first word, "whether," is spelled with "wh" instead of "w" because it is pronounced with the /hw/ sound. The second word, "no," is spelled with "o" instead of "ow" because it is pronounced with the /oʊ/ diphthong. "Whether no" is often used to express uncertainty about something, as in "I'm not sure whether no one will show up to the party."
"Whether no" is not a standard phrase or term used in the English language. However, when analyzing it as two separate words, it is possible to provide some interpretation of the meaning.
"Whether" is a conjunction often used to introduce two or more alternatives or possibilities. It is commonly used to express a choice between two or more options. For example, "I couldn't decide whether to go to the beach or stay at home." In this context, "whether" introduces a question regarding a range of possibilities.
On the other hand, "no" is a determiner, adverb, or exclamation that negates or denies something. It is used to express the absence or nonexistence of something. For instance, "There are no seats available" or "No, I don't want any dessert."
Considering these definitions, the phrase "whether no" does not have a clear or established meaning on its own. However, it is possible to speculate that it could be used to express doubt or confusion about the absence or nonexistence of certain possibilities. Without any additional context, it is difficult to determine a more precise definition for this particular phrase.
