Part vs partie?

Question

Quelle est la différence?

Accepted Answer

Hi Ann and Chris, 
‘Une part de’ means ‘a share/ slice of something’ ...
You might buy/eat/want -
Une part de gateau
Une part de galette 
Une part de Brie
Or you mights wish for ‘une part de bonheur’ which is your slice of happiness!
So, as you can see from those examples it represents the idea of a cake-like shape which can be shared out in triangular pieces.
Hope this helps!

Answer

That's a difficult one. There definitely is a difference and there are phrases where you can use only one but not the other. They translate as the same word in English, though, which makes them difficult to ceem them apart (pun intended;)

Maybe la part is more of a share of something. Whereas la partie is a part of something.
