IF CLAUSE

Hi,
A comma question in IF caluse...

If X is Y and Z is K, then A is B and C is D.
If X is Y, and Z is K, then A is B, and C is D.

Which is correct?

Or are they both wrong? Then what is the correct sentence?

Thanks.

Hi, If your question is more about strict logic and less about "normal" English, I won't offer an opinion. Are you doing a course on logic? Otherwise, I'd say that I favour the version without a comma, unless the expressions that you are representing here by letters actually consist of a lot of words.

HI,
Thanks much for the reply.
I used the alphabets for clarity, but really, I am referring to "real" sentences.

For example:

If I went to go to a picnic and I ate a lot of food there, then I would become fat and I would have to be on diet again.

It seems that the correct grammar is without comma because it is a "set" of ideas.
BUt what confuses me is that "

Hi Clive,
Ok, so if the two "ideas" comprise ONE condition, there should be no comma.
So, in this case, since the two ideas udner "IF" and the two under 'THEN" are connected,the correct version is:

If I went to go to a picnic and I ate a lot of food there, then I would become fat and I would have to be on diet again.

Is that right?

If so, thanks!

Hi,

Sounds fine to me.

If I went to go on / to a picnic and I ate a lot of food there, then I would become fat and I would have to be on / to go on a diet again.
