Word Origin & Etymology

Borrowed from Late Latin, from Ancient Greek ὦ μέγα (ō mega), literally meaning 'great O' (to distinguish the long vowel Ω from the short vowel omicron, 'little O'). Its figurative meaning of 'the end' derives from the biblical phrase 'I am the Alpha and the Omega' in the Book of Revelation.
