The word "Halled" is spelled with a double "l" in the middle, as opposed to a single "l" in the common word "halved". This spelling difference is due to the pronunciation of the word. "Halled" is pronounced with stress on the second syllable, with a long "a" sound and a separate "l" sound. This is indicated in IPA transcription as /ˈhæld/. The double "l" helps to emphasize the pronunciation of this second syllable, distinguishing it from the similar sounding word "halved", which is pronounced with stress on the first syllable and a shorter vowel sound.
