I heard it many times but I haven't really pondered on that. We can hear these following sentences in our daily lives:
- May God bless you.
- May God be pleased with you.
- May God accept your prayers.
But why do we use "May" at the beginning of the sentence? Apparently, it doesn't make the sentence a question but more polite and respectful towards the God maybe? I cannot tell I heard this structure in any other sentence but religious ones. Which grammar rule does it belong to? And how do we use it in different forms?
