“By any chance…”

Very common in spoken English, by any chance (“per caso”) is used to ask if something is true or possible and usually comes at the end or in the middle of a question:

• “Do you have time for a coffee by any chance?”
• “Could you by any chance meet us at the restaurant at 8 o’clock?”
• “Do you know Marco by any chance?”
• Is there by any chance a Tube station near here?”
