Here are some words derived from the root "net-":
* Cognition: The process of knowing, understanding, and becoming aware of something.
* Agnostic: Someone who believes that it's impossible to know whether or not God exists.
* Recognize: To identify someone or something as familiar.
* Incognito: Hidden or disguised.
