The spelling of the word "haddest oneself" can be explained through its phonetic transcription in IPA (International Phonetic Alphabet). The first syllable "had" is pronounced as /hæd/, the second syllable "dest" is pronounced as /dɛst/, and the final syllable "oneself" is pronounced as /ˈwʌnsɛlf/. The word "haddest" is an archaic form of the verb "have" and "oneself" is a pronoun. Therefore, "haddest oneself" means "you had yourself". Although rarely used today, it was common in the Middle English language period.
The phrase "haddest oneself" is not commonly used in modern English. However, if we break it down, we can analyze its etymology.
"Haddest" is the past tense of the verb "have" in the second person singular form. In Old English, "haddest" was used to indicate possession or ownership.
"Oneself" is a pronoun that refers to the person speaking or author of a statement.
So, when combined, "haddest oneself" would suggest an individual possessing or owning themselves. The etymology of the individual words can be traced back to Old English and the Germanic roots of the English language.
