The term 'disenfranchise' (14 letters) is a synonym for 'deprive of voting rights'. It is used to describe the act of taking away the right to vote from a person or group of people. This can be done through legal means, such as passing a law that restricts voting rights, or through more informal methods, such as intimidation or violence. Disenfranchisement has been used throughout history to limit the political power of certain groups, such as women, racial minorities, and the poor.
