整
整 – Zheng3 – Neat, Orderly, Rectify, Entire
This word, and probably lots of the words I give you, don’t really mean anything on its own. It is used in conjunction with other words to mean something.
For instance:
整理 – Zheng3 Li3 – Neat Arrange — Clean Up
整潔 – Zheng3 Jie2 – Neat Clean — Neat and Clean
