The correct spelling of the word "haddest feeling" is actually "hadst feeling". In IPA phonetic transcription, it would be /hædst ˈfiːlɪŋ/. The word "hadst" is the second person singular past tense form of the verb "have". When combined with "feeling", it represents the past tense of the phrase "have a feeling". While this archaic phrasing is not commonly used today, it is important to understand its correct spelling and grammar for historical and literary purposes.
