Abelus

• Abē̆l (the vowel should be short by etymology, but it is written as long in a macronized adaptation of Lhomond's Epitome Historiae Sacrae)
• Habel (more precise borrowing from Greek)

Borrowed from Ancient Greek Ἅβελ (Hábel), itself from Biblical Hebrew הֶ֫בֶל‎ (heḇel). The vowel, while short by etymology, is shown to be carrying stress by the descended Italian Abele and Spanish Abel.

• (Classical) IPA^(key): /aˈbeː.lus/, [äˈbeːɫ̪ʊs̠]
• (modern Italianate Ecclesiastical) IPA^(key): /aˈbe.lus/, [äˈbɛːlus]
