How to Use The Suffix -ize
The suffix -ize can be added to almost any noun or adjective to turn it into a verb. There are people who say that the suffix -ize is overused. This means that people use it too much. Some people feel that many of the words made with this suffix are not elegant and don’t have any real place in English.
Here are my thoughts.
I feel there is a large difference between friendly English conversation and published English work like magazines or newspapers, and news or information programs.
If you are having an informal conversation with friends or relatives, and you add the suffix -ize to make a verb that helps your story, I think it’s fine.
Being understood when sharing an idea is the most important thing. If your message was understood, that is successful communication.
You did it!
We could apply the same strict standard to the suffix -ish. This is another suffix that is used very freely to modify words with the meaning of approximate or close.

Those who have a problem with the suffix being overused are usually talking about published English work.
Material that is printed and shared is often held to a higher standard.
In casual conversation you should feel free to communicate in a way that you are confident will be understood.
