What does zation mean?

Answer 1

Nothing. It is used as a tradename and username by some people. Although it does form the end of words like organization and civilization, it is not a word itself, nor is it even a suffix. The real suffix is "-ation" as found not only in the above two words but also "relation" and "speculation" and many others. The suffix is used to change verbs into nouns, meaning the act of doing whatever the verb says. Want a word that means the act of speculating? Speculation. One that means the act of civilizing? Civilization. The act of equalizing? Equalization.

Sometimes the words have gone their own way. Organization means not only the act of organizing but also a group of people who are organized.

Answer 2

The suffix "zation" at the end of a word usually indicates the process or act of turning something into the root word. For example, "organization" refers to the process of organizing something, "optimization" refers to the act of optimizing something, and "modernization" refers to the process of making something modern.
