What does unsorted mean?
“Unsorted” describes something that has not been arranged, classified, or otherwise put into a deliberate order. It is especially common in references to mail, email, files, data, and lists, where items may be readable or usable but have not yet been grouped or processed according to their intended categories. The word can also carry a mild evaluative implication: an unsorted collection may be difficult to navigate, inefficient, or simply waiting to be organized. Nevertheless, it is more precise than “messy,” because disorder does not necessarily imply damage, poor quality, or untidiness. “Unsorted” is also standard technical vocabulary in computing, where it can distinguish information that has not been ordered or categorized from data that has undergone the relevant sorting process. As an adjective, it is typically placed before a noun, as in “unsorted mail” or “unsorted data,” but it can also occur after a linking verb.

Where does unsorted come from?
The adjective was formed in English by adding the negative prefix un- to sort. Sort came through Old French from Latin, ultimately from a Latin word meaning “kind,” “chance,” or “lot,” which developed the sense of arranging things by kind or class. The unsorted form developed later as a natural English negation of the sorting process and now refers broadly to material that has not been put into order.
How unsorted is actually used
The word is standard and neutral in general English, especially in administrative, postal, publishing, and computing contexts. It normally appears before a noun, although predicative use is also grammatical.
Easily confused with unsorted
