A more thorough explanation: Protestation is a formal declaration or statement made to assert or affirm something, often in a legal context. It is a solemn declaration made by a person to affirm the truth of a statement or to disclaim responsibility for something.
Example: The defendant’s protestation of innocence did not sway the jury, who found him guilty of the crime.
