έναςa, an (masculine indefinite article)Etymology
Greek ο is the masculine singular form of the definite article. It descends from Ancient Greek ὁ, part of the demonstrative set ὁ, ἡ, τό that once meant 'this' or 'that' before it weakened into 'the'. The ancient form traces back to the Proto-Indo-European demonstrative stem *so, the same source that gave English 'the' and 'that'.
