A stipend is a regular fixed sum of money paid for services or to defray expenses, such as for scholarship, internship, or apprenticeship. It is often distinct from an income or a salary because it does not necessarily represent payment for work performed; instead it represents a payment that enables somebody to be exempt partly or wholly from waged or salaried employment in order to undertake a role that is normally unpaid or voluntary, or which cannot be measured in terms of a task (e.g. members of the clergy).
