Pronunciation: [hˈadəst fˈɪt] (IPA) 
"Haddest fit" is an archaic form of the phrase "had a fit". In IPA phonetic transcription, it would be written as /ˈhædɪst fɪt/. The "dd" sound in "haddest" is a result of the Old English "th" being pronounced as "d" in this particular verb form. This spelling is no longer used in modern English, and "had a fit" is the standard form. However, it may appear in literature or historical documents.
"Haddest fit" is an archaic term that combines the auxiliary verb "haddest" and the noun "fit," both of Middle English origin. This phrase is used to describe a state of extreme anger, outburst, or tantrum.
The term "haddest" is the second person singular past tense form of the auxiliary verb "have," which indicates possession or ownership. In this context, "haddest" suggests that the individual has already experienced or possessed the fit in the past, referring to a previous episode of uncontrolled rage or emotional turmoil.
On the other hand, "fit" typically refers to a sudden outpouring of strong emotion or behavior, such as anger, excitement, or even laughter. It denotes a state of being struck by a particular feeling or impulse that overwhelms an individual's rationality temporarily.
When combined, "haddest fit" portrays an intense display of emotional instability or an uncontrollable outburst from an individual, usually due to anger or annoyance. This phrase could relate to someone experiencing a sudden wave of rage or an overwhelming tantrum-like behavior.
However, it's crucial to note that "haddest fit" is primarily found in older English literature or historical texts, having fallen out of commonplace usage in contemporary English.
