[Casiopea]

Are these correct? If not, why?

1. Thank God. (Why is this correct?)
2. Thank Jack. (How come this is wrong?)
3. Thanks God.
4. Thanks Jack.

1. and 2. are OK (i.e., Ask God/Jack for thanks. Thank them/him (Verb + Object)):

Thank God. (Do this: Give thanks to God)
Thanks, God. (Thank you from God)

Thank Jack is OK (i.e., Do this: Give thanks to Jack for all his help). Mind you, Thank God! or Thank God is an idiomatic expression.

If 3. and 4. mean, Thanks from God/Jack, as in the closing of a letter or an email, then a comma is required in order to separate the object of 'from' from the noun "Thanks".

Thanks from God/Jack.
Thanks, God/Jack.

Note that, "Thanks" is a noun:

I am giving/sending my thanks to God/Jack.

Thanks Jack (My thanks to Jack)
Thanks, Jack. (Thank you form Jack)

All the best,

Thank God. (Do this: Give thanks to God)
Thanks, God. (Thank you from God)

Are these correct? If not, why?
1. Thank you. (correct)
2. Thanks you. (Is this incorrect? Why? #3 is correct but #2 isn't?)
3. Thanks Jack. (correct)
4. Thank Jack for it. (correct)
5. Thank you for it. (Is this correct? If not, why?)

Thanks Jack (My thanks to Jack)
Thanks, Jack. (Thank you form Jack)

So these mean the same thing? What's the point of the comma?
6. Thanks Jack. (My thanks to Jack)
7. Thanks, Jack. (Thank you from Jack)
So with the comma there it means 'form Jack'? Without the comma it means 'to Jack'? How do you what the comma mean? How do you know if it doesn't mean 'by' or something else?

8. How do you what does the comma mean? (This is incorrect right? Because there are two questions? Eg. 'How do you know? What does the comma mean?')
