Difference between TO, AND, IN ORDER TO

[Jesus1]

Hello!Thanks for all your replies. And thanks again!

Can I use all of them to mean the same thing?


I shall open it 'TO' see if it?s true what you?re saying.
I shall open it 'IN ORDER TO' see if it?s true what you?re
saying
I shall open it 'AND' see if it?s true what you?re saying.


2.- You don?t go to that club ?cause
the music, you say, is too loud.

Is it correct to use that "you say" between
commas?

Thank you very much!

Jes?s

1 - To and in order to indicate purpose. Therefore, your first two sentences amount to the same thing. And means 'also', 'as well as'. So, the third sentence is a slightly different way of saying it. I would only change the word order:

I shall open it to/in order to/and see if what you're saying is true.

2 - You don?t go to that club ?cause the music, you say, is too loud. Yes, commas between the phrase 'you say' are correct and necessary. You can also place the phrase at the end of the sentence, after a comma.
