Etymology Origin:
The word function traces back to Latin functio (performance, execution), from fungi (to perform, discharge). It entered English via Old French fonction in the 16th century, initially referring to religious duties. Over time, its meaning expanded to include mathematical relations (18th century) and social events (19th century), reflecting its core idea of "purposeful action."
