Λουκᾶς (Ancient Greek)

Where does "Λουκᾶς" come from?

The Ancient Greek name 'Λουκᾶς' was formed using the suffix '-ᾶς' as a hypocoristic of either 'Λούκιος' or 'Λουκανός', or a combination of both[1]. The intermediate form 'Λούκιος' itself came from the Latin 'Lūcius', which ultimately traces back to the Proto-Indo-European root '*lewk-' meaning 'brightness' via Latin 'lūx' and Proto-Italic '*louks'[2].
