IPA: /ʌnˈsɔːrtɪd/
KK: /ʌnˈsɔrtɪd/
Not arranged in a specific order or category; mixed together without organization.
The files were left unsorted on the desk, making it hard to find what I needed.
Unsourced from Old English 'unsorted', where 'un-' (meaning not) is a prefix indicating negation, and 'sorted' comes from the root 'sort' (from Latin 'sors', meaning lot or fate). The word 'unsorted' means not arranged or categorized.
Think of 'not' ('un-') being added to 'sorted', which means arranged. This helps you remember that 'unsorted' refers to things that are not arranged.
