Question

is it correct English to say that Happy Sunday

Answers

Answered by GPT-5 mini
Yes — "Happy Sunday" is fine as an informal greeting. It works like an interjection: e.g. "Happy Sunday!" or "Happy Sunday to you!"

Notes and alternatives:
- For a fuller sentence: "Have a happy Sunday" or "I hope you have a great Sunday."
- In formal writing, prefer "I hope you have a pleasant Sunday" or "Enjoy your Sunday."
- If you want to report it, say: "Is it correct to say 'Happy Sunday'?" (You don't need the word "that" before the quoted phrase.)
