"Come sai."

Translation: As you know.

I really hate it when they throw sentence fragments at you.

[gedung]

it sounded like "come stai" to me

[jaye16]

No, it was fine. But we are more used to "come stai".

[nictheman]

Now just a question of Italian semantics/syntax. Would I be correct in saying that this is only "As you know" or "Like you know" because of the full stop? If it were a question mark, the sentence would actually read "How do you know?".
If so, that is so cool haha.

[marziotta]

If I would make a question I would rather say "Come lo sai?" (How do you know IT?)

But that's a special case, usually adding a question mark can make a question.

"Come" translates a lot of stuff. :D

Even if we Italians never realise it...

[nictheman]

Haha I had a feeling you'd say "Come lo sai" -- I found the Clitic Pronouns lessons very very difficult so I spent (and still spend) a lot of time on them.

If there were a question mark, could you translate this as how do you know?

[CompuChip]

I guessed this means "how do you know?". Why does come suddenly mean "as"?

[KarenColle]

I agree totally! My exercise had a question mark after "come sai"...so I also translated it as "how do you know?"

[noeczi]

I'm so ridiculously proud of myself for figuring this one out... :D
