The spelling of "haddest relations" can be explained using IPA phonetics as /ˈhædəst/ /rɪˈleɪʃənz/. The word "haddest" is derived from the archaic English verb "to have" in the second person singular form. The addition of "-est" is used to denote the past tense. Meanwhile, "relations" is spelled phonetically the same way as its modern counterpart. "Haddest relations" is a phrase commonly used in older texts to refer to having sexual intercourse with someone.
