"Injury" is harm to a client, the public, the legal system, or the profession which results from a lawyer's misconduct. The level of injury can range from "serious" injury to "little or no" injury; a reference to "injury" alone indicates any level of injury greater than "little or no" injury.
"Intent" is the conscious objective or purpose to accomplish a particular result.
"Knowledge" is the conscious awareness of the nature or attendant circumstances of the conduct but without the conscious objective or purpose to accomplish a particular result.
"Negligence" is the failure of a lawyer to heed a substantial risk that circumstances exist or that a result will follow, which failure is a deviation from the standard of care that a reasonable lawyer would exercise in the situation.
"Potential injury" is the harm to a client, the public, the legal system or the profession that is reasonably foreseeable at the time of the lawyer's misconduct, and which, but for some intervening factor or event, would probably have resulted from the lawyer's misconduct.
