Past participles of verbs are often spelled differently than their homophones and homonyms. Whether the farmer baled hay or the sailor bailed water, they both pronounced it the same, but if they wrote someone about the experience, they spelled it differently. Sometimes they aren't even pronounced the same. The simple past tense of "break" is "broke," whereas the simple past tense of "brake" is "braked." The car braked and the windshield broke. The same is true of the homonyms for "lie." She lay in my bed and lied to me. It’s not true of King Alulim, who some Sumerian texts claim to have been at the throne during the time of Noah’s flood. He reigned until it rained. Homophones in this case. A tangentially related matter is the word "hang," whose past participle changes once it is a means of execution—a picture is hung, a man is hanged. That's gotten a little fuzzy in recent years, but the classic western hangin' judge utterance (and who would know better) is "hanged."
