2432: θεός & Deus: Unrelated Aug 18, 2021

The Greek θεός (theos) meaning 'god' or 'divine' and the Latin 'deus' meaning 'god' are not related, despite the clear similarity in sound and meaning. θεός comes from a root meaning 'to place' in Proto-Indo-European while 'deus' is from a root meaning 'sky' and is related to the Greek 'Zeus' and 'Iupiter' as well as the 'Tiw' of 'Tuesday'. The Greek word is also related to the Latin 'fēriae' (festival), 'fānum' (temple), and 'fēstus' (festive).
