Sense: adjective/1
Voluntary, optional, and elective all describe choices, but they differ in context. Voluntary emphasises that an action is done without force or payment — you choose to do it because you want to. Optional focuses on whether something is required or not; an optional activity can be skipped with no consequence. Elective usually refers to courses or positions that people select from available options. Unpaid specifically highlights that no money is received for the work, regardless of whether the person chose it freely. Willing describes a person's attitude of readiness rather than the nature of the action itself. For example, you might make a voluntary donation to a charity, attend an optional training session after work, or serve on an elective committee.

Etymology
Voluntary comes from the Latin word 'voluntarius', meaning 'willing, of one's own free will'. This is based on 'voluntas', meaning 'will, wish, desire', which in turn comes from 'velle', meaning 'to wish or to want'. The word entered English through French in the late 14th century. The noun sense referring to organ music first appeared in the 16th century, originally describing a piece played at the performer's own choice.
