The word "haddest over" is spelled using the Middle English language. In IPA phonetic transcription, it would be pronounced /ˈhæd.ɪst ˈoʊ.vər/. "Haddest" is the second person singular past tense form of the verb "have" and means "you had." "Over" means "across or beyond." This phrase may be used in a sentence such as, "If thou haddest overstepped thy bounds, thou wouldst have been punished." The spelling of this word reflects the evolution of the English language over time.
The term "haddest over" is not a recognized word in English. "Haddest" is an old form of the verb "to have" and "over" is a preposition meaning "above" or "across". However, the combination "haddest over" does not have a specific etymology as it does not form a separate word or phrase with a distinct meaning. It appears to be a combination of two separate words without a specific linguistic origin.
