Translation:The boy drinks milk.
γάλα sounds like a root of galaxy. Let me check...
And it's true: from Ancient Greek: γαλαξίας galaxías, “Milky Way”.
The γάλα really sounds like agar.io ... hmmm...
The boy's drinking milk? – gives an error.
Yes, contractions of noun + verb are not accepted automatically but have to be entered manually as a separate alternative, so this is usually not done. I recommend not using contractions on Duolingo.
Is γ sounds like "v" here in γάλα?
