A more thorough explanation:

Definition: A volunteer is a person who chooses to do something without being paid or forced to do it. This can include helping others, working for a cause, or participating in an activity or event.

Examples:

• Volunteering at a local animal shelter to help care for animals in need.
• Participating in a beach cleanup event to help keep the environment clean.
• Helping out at a community fundraiser to raise money for a good cause.

These examples illustrate the definition of a volunteer because in each case, the person is choosing to give their time and effort to help others or make a positive impact. They are not being paid or forced to do so, but are doing it out of their own free will and desire to make a difference.
