The word "haddest a right" is spelled using Middle English spelling conventions, and is pronounced /ˈhædəst ə raɪt/. In modern English, the word "haddest" would be spelled as "hadst" or "had", while the phrase "a right" would remain the same. The use of archaic spelling conventions can make reading and understanding older texts challenging for modern readers. However, it can also provide insight into the evolution of the English language and the ways in which language use has changed over time.
