"On Wednesdays I drink wine."
What is the problem ? my answer is: II mercoledi io bevo vino, and I got an error, please explain because I am confused.
You have put "il" instead of "i". With "il" your translation is "On Wednesday I drink wine" .
But doesn't il mercoledì mean 'on Wednesdays' as well?
Le mercredi does in French...
"il" is singular, "i" plural, so "il mecoledi" would be on Wednesday, not on Wednesdays. Or so I believe.
