The correct spelling for the phrase "would will not" is /wʊd wɪl nɒt/. The word "would" sounds like the word "wood" with a "d" at the end, and is pronounced with the short "u" sound. The word "will" is pronounced with a short "i" sound, like the word "fill", and the "ll" is pronounced like a single "l". "Not" is pronounced with a short "o" sound and a silent "t" at the end. This phrase is commonly used to express a negative future scenario that is unlikely to happen.
