"Αυτοί σου διαβάζουν μία εφημερίδα."

Translation: They read you a newspaper.

[Aline2022]

Incorrect English. One does not say : they read you. The correct answer is : they read to you

[JamesGritt]

"They read to you a newspaper?" Perhaps correct (?), but clunky. "They read you a newspaper" is more natural, at least in American English.

One does say on the other hand, "They read a newspaper to you."

[DelynVeaud]

How can we know its "αυτοι" and not "αυτη"? Sounds the same ?

[G.Georgopoulos]

They do sound the same, but the verb forms will be different, too.

The best English translation is exactly as shown. The secondary translation? "They read a newspaper to you." (I'm a professional legal and scientific editor in English, an English and ESL teacher, and a native English speaker.)

What's the difference between σου and σας? Could σας be used in place of σου? How are their meanings different?

[D_..]

Σου is the singular form, σας is the plural and the formal (i.e. even if addressing only one person) form. Use accordingly. :)
