"Does he wear a tie?"
should there not be an αυτος at the end? there is nothing here to show the masculine/feminine. What would the difference be between this and "does SHE wear a tie?"
You have hit the jackpot. Of course, there is nothing to indicate whether it is a he,she or it. This is exactly what we have in the incubator >> he/she/it. Any of these are correct translations.
Why is Πίνει νερό το κουτάβι in the suggestion drop down box when touch "Does"
I have just checked the incubator and there is no sign of such a mix -up. What kind of exercise was it? If you have a screenshot you should report this since it is clearly a technical error.
I entered "Φοράει αυτός μία γραβάτα;" and it was accepted as correct...not sure if that is proper but it worked.
