Is there a word for 'items not in a set'?
Here is the desired usage: when I organize things into boxes by source (could be brand, author, sender... any logical way to group items) I have a box for source X, a box for source Y, etc. I can use X, Y as the labels for the boxes. Now all the rest goes into a box, what should I label it with?
In my mother tongue there is a word for that, literally 'scattered' in English. I don't believe 'scattered' is the right word here.
In English, the closest word I could think of is 'miscellaneous', which may work for the label of the box, but the meaning isn't the same as what I want. Other options include 'ungrouped' and 'uncategorized', which aren't exactly true because the items in that box are indeed categorized. They are categorized as 'not in a collection'.
What is the right word?
