The phrase “c’est”, as we learnt in 3 Minute French – Course 1, means “it is”. However, you can also translate it as “that is” or “this is”
c'est bon – it’s good / that is good / this is good
c’est fantastique – it’s fantastic / that is fantastic / this is fantastic
However, most of the time, you can emphasise the “that” by adding the word “ça”
ça c’est bon – that is goodça c’est fantastique – that is fantastic
You could imagine putting a comma after the word “ça”, which you can do, and you get this:
ça, c’est fantastique – that, that’s fantastic
It really emphasises the word “that”
In fact, you can even put the word “ça” on the end of the sentence, too:
c'est bon, ça – it’s good, that / that one is good
c’est fantastique, ça – it’s fantastic, that / that one is fantastic
c’est pour moi, ça – it’s for me, that / that one is for me
You can even say this nice phrase:
c'est ça – that’s it / that’s rightoui, c’est ça – yes, that’s right
