How to say I don’t know in Italian
Before we embark on our journey of saying I don’t know, we need to make sure we do know the differences between two verbs: sapere and conoscere. You may already be familiar with these verbs, but let’s do a quick review.
The difference between “sapere” and “conoscere”
In Italian, there are two verbs used to talk about “knowing” or “not knowing” something or someone: sapere and conoscere. These two verbs are not interchangeable, so it’s important to understand how to use each one correctly. Don’t worry, though! We’ve come up with a handy table to discuss the main differences.
On a simple level, use sapere when referring to knowing something and conoscere when talking about knowing someone. Sapere often refers to being aware of something, whereas conoscere refers to being familiar with a person, place, thing, or topic.
Let’s go into a bit more detail with this table.
Non so che ore sono.
Non conosco Marco.
Non so nuotare.
Non conosco bene la città.
Sai dove posso prendere un buon caffè?
Conosci un posto buono per prendere un caffè?
The last row in the table has two different sentences that essentially ask the same thing: Where can I get a nice cup of coffee?, but notice how the verbs are used differently. In the first question, sapere refers to being aware of where to get a coffee, whereas conoscere refers to the specific place (the coffee bar).
Keep in mind that these are both irregular verbs, so you’ll need to conjugate them accordingly. Let’s conjugate both in the present tense:
|Lui / Lei
Now that we know the main differences between these two verbs, check out the following table with a few general, useful phrases!

You might already know that hand gestures and facial expressions can make all the difference when speaking Italian, and this rule really holds true with the first phrase in the table below: Boh!
Boh! is an exclamation that is instinctive for many Italians. It’s an expressive way to say something like I dunno, and I like to think of it as a verbal shoulder shrug.
