"He eats garlic."
Translation:Lui mangia dell'aglio.
No, in English "He eats some garlic." is talking about an unspecified amount of garlic (Old English "He eats of the garlic.") and we often just say "He eats garlic." in the same situation, as again the amount is unspecified; even though, "He eats garlic." could also be a generalization meaning "Garlic is something that he eats." So, from the Italian to English translation both "He eats some garlic." and "He eats garlic." should be accepted. So, when translating from the English "He eats garlic.", you again have more than one Italian translation to use.
I'm a little confused. I'm looking at this table: http://en.wikibooks.org/wiki/Italian/Prepositions and can't seem to figure out why it's dell'aglio. The contracted form is used instead of the more cumbersome "della aglio", right? But how is this possible, as aglio is masculine, meaning that it requires the "il" article. Thanks for any replies!
