The word 'stipend' originates from Latin stipendium, which itself is a compound of stips (a small coin, contribution) and pendere (to weigh out, pay). The literal concept was of a weighed-out payment, specifically a soldier's pay. This term entered English via Old French stipende in the 15th century. Over time, the meaning broadened from a soldier's wage to any fixed periodic payment, especially one associated with professional or academic roles, while retaining its core sense of a formal, regular monetary allowance.
