✕Common Mistakes
Kann ich das Klo?
The preposition ‘auf’ (accusative) is required; ‘das Klo’ alone sounds like you’re naming the object, not asking to go there.
Kann ich zu Klo?
‘zu’ takes the dative and is not used for moving toward a place like a toilet. Use ‘auf’ (accusative) instead.
Kann ich Klo?
Dropping the preposition makes the sentence ungrammatical. The correct structure is ‘auf das Klo’ → ‘aufs Klo’.

Entschuldigung, darf ich kurz auf die Toilette?

Cultural Tip
‘Klo’ is widely understood across German‑speaking countries but is considered informal and a bit slangy. In northern Germany you’ll also hear ‘WC’ (pronounced ‘ve‑t͡se’) and in Austria ‘Klo’ is common, while in Switzerland ‘Toilette’ or ‘WC’ is preferred. When you’re unsure about the level of formality, choose the longer ‘Toilette’ version.
