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
