noun, na-adjective, noun which may take the genitive case particle 'no'
unsorted; unorganized; pending; incomplete
Describes something not yet sorted, arranged, or processed. Often used for documents, data, tasks, or ideas that are still in a raw or unfinished state.
Unsorted documents are piled up on the desk.
This data is still unorganized, so it cannot be used for analysis.
Compound of 未 (mi, 'not yet') + 整理 (seiri, 'sorting, organization'). The prefix 未- is productive for forming nouns meaning 'not yet done'.
