However, there are a few prefixes that relate to the concept of information or knowledge:
* In-: This prefix means "in," "into," or "not." It can be used to create words like "inform" (to put information into someone), "inactive" (not active), or "incompetent" (lacking competence).
* Mis-: This prefix means "wrong" or "bad." It can be used to create words like "misinform" (to give someone wrong information), "misunderstand" (to understand something incorrectly), or "mislead" (to lead someone astray).
* Dis-: This prefix means "apart," "opposite," or "not." It can be used to create words like "disinform" (to provide false information), "disengage" (to withdraw from something), or "disapprove" (to not approve of something).
* Re-: This prefix means "again" or "back." It can be used to create words like "reinform" (to inform someone again), "reinvent" (to invent something anew), or "reexamine" (to examine something again).
These are just some examples, and many other prefixes could relate to "informed" depending on the specific context.
