It is correct English to say "thank someone for something" eg "My wife and I thank you for your kind invitation to your daughter's wedding"
thank you
When someone says congratulations to you, or when someone congratulates you, say, "Thank you".
you say:"Thank you so much for this invitation"
just say "i thank for giving me an opportunity to do this ,it it was a pleasure."
Say Thank You for helping me in return..
you could say Thank You
You say 'You're Welcome'
