What is the prefix for conduct?

There is no single prefix specifically for "conduct". However, depending on the context, you could use prefixes like:

* Mis-: for bad or wrong conduct (e.g., misconduct)

* Mal-: for bad or wrong conduct (e.g., malpractice)

* Dis-: for the opposite of conduct (e.g., disconduct, though this is less common)

* In-: for the opposite of conduct (e.g., in conduct, meaning lack of conduct, though this is not a typical word)

It's important to understand the specific meaning you want to convey when choosing a prefix.
