When Virgil wrote "quos ego", what branch of the Indo-European languages was he using?
Quos ego: Quos ego (Latin, literally 'Whom I') are the words, in Virgil's "Aeneid" (I, 135), uttered by Neptune in threat to the disobedient and rebellious winds. Quos ego:  Virgil's phrase is an example of the figure of speech called aposiopesis.
