早 and 早上好 have the same meaning?

[Nork02]

Hi all!

can I use 早 instead 早上好?....if so, can I use them in the same situation/context?

Thanks

Exactly the way you say "Morning" instead of "Good morning".

monto's analogy is accurate. Just note that some speakers, perhaps Taiwanese or southern Mainlanders, use 早安 (zǎo ān) instead of 早上好. I said 早上好 to a Taiwanese friend, and he was like "What the hell? Morning good?" So I tend to use 早安 or just a plain old 你好 to be safe.

早is not very formal, but it's short, so people use it in daily life especially in casual life.

早上好 is a formal use, you can use it in formal occation or meet one people in the morning for the first time.
