    let
    Source = {"A", "B", "C"},
    w = List.TransformMany(
        List.Skip(Source), 
        (x) => {x, {x}},
        (x, y) => if y is text then {Source{0} & y} else {Source{0}} & y

How is this a concatenation of lists?

    Ok, you could say mapping, but as I take  { "a","b","c"}  and end up with  { "a,b"}  how is this not 
    conctenation?

      It might be a concatenation/permutation of the values in a list but not a concatenation of lists.

       

      Maybe a more real world example would have helped to understand the ask (and the reason).
