The spelling of the phrase "willing will not" can be confusing for non-native English speakers due to the silent "g" in the word "willing". The IPA phonetic transcription of "willing will not" is /ˈwɪlɪŋ wɪl nɒt/. The "ng" sound in "willing" is represented by the symbol ŋ, and the stress is on the first syllable. In contrast, "will not" is spelled as it sounds, with the stress on the second syllable of "not". Mastering the spelling of English words requires practice and familiarity with the language's various quirks.
