The word 'voluntarily' means that a person chooses to do something without being forced to do so. For example, if someone volunteers to help with a community service project, they are doing it voluntarily. It can be used in situations where a person is not obligated to do something but chooses to do it willingly. You could use it in a sentence like "She voluntarily offered to stay late at work to help finish the project."
