LINQ: How do I compare two elements?

I have a list of strings and if one element is a substring of another element, I want to remove that shorter element.

So, 

{abc, def, ghi, ab, cd, ef} => {abc, def, ghi, cd}

I tried: 

list = list.Where((x, y) => x.Item1 != y.Item1 && x.Item1.Contains(y.Item1) == false);

but somehow y is an integer.

The overload of Where that you used is for filtering with an element and the index. You need to use the "regular" Where, like this:

var res = list.Where(x => !list.Any(y => x != y && y.Contains(x)));

Demo.
