The spelling of the word "repentanced" may seem a bit confusing to some, but it can be easily explained through its phonetic transcription: /rɪˈpɛntənst/. The "-ance" suffix is often added to verbs ending in "-ant" to form a noun indicating the state or quality of the verb. In this case, "repented" becomes "repentance." Adding the "-d" to the end to make it past tense ("repentanced") may seem odd, but it is actually a common usage in older texts and can still be used today.
