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 Latin) IPA^(key): [aˈbeː.ɫʊs]
• (modern Italianate Ecclesiastical) IPA^(key): [aˈbɛː.lus]
