Là fuori – locative adverb

✕Common Mistakes
Sei attento là fuori.
Use "stai" for the imperative; "sei" is the present indicative and does not convey a command.

The adjective must match the gender of the person you’re speaking to. "Attenta" is correct only if you’re addressing a woman.
Stai attento là fuori?
Adding a question mark changes the meaning to a question. The phrase is a statement/command, not a question.

Cultural Tip
In Italy, the informal imperative "stai attento" is common among friends, family, or when speaking to children. For adults you don’t need to sound overly formal, but if you’re addressing a stranger or a superior you’d switch to "stia attento". Also, "là fuori" adds a slight emotional distance, often used when the speaker is inside or in a safe place while the listener is about to step into a potentially risky environment.
