Puis-je

Question

This was my first time coming across the inverted questions.. 'puis je'
 
 
I read the lesson that that's more formal and 'est-ce que' is used more colloquially. I thought you could always replace est-ce que with just the interogative + subject + verb so I put 'Que je peux faire...' which was marked wrong. Is this wrong with these inverted questions?
 
And also in the lesson it mentioned "statement order"'questions being a possibility. What are these?

Accepted Answer

Bonjour Becky,

Qu'est-ce que je peux faire pour vous ? = What can I do for you?
Que puis-je faire pour vous ? = What can I do for you?
Est-ce que je peux faire quelque chose pour vous ? = Can I do something fpr you?

Take a look here:

I hope this is helpful.
Bonne journée !

Answer

Salut Becky,To say "Puis-je ?"  is equivalent to asking "May-I ?" in English.My experience once in a restaurant in Lyon asking for another carafe of water, caused the waiter to comment very favourably.I was quite taken aback, perhaps he was not used to polite requests.Bonne JournéeJim
