整理（せいり、seiri）
- arrangement/sorting

The Japanese word 整理, pronounced せいり (seiri), primarily means "to sort," "to arrange," "to organize," "to put in order," or "to tidy up." It encompasses the act of bringing order to something, whether it be physical items, information, or thoughts. It implies a process of cleaning, classifying, and arranging things to make them more manageable and easier to use.
