What was “serf labor services” often called in French history terms?

The story behind the answer

In French history, corvées were obligatory, unpaid labor services that peasants or serfs owed to a lord or the state. Instead of money, people “paid” with days of work: plowing the lord’s fields, harvesting, carting timber, or maintaining roads and bridges. Under the Ancien Régime, a royal version (corvée des chemins) compelled rural communities to build and repair highways.

These demands were widely resented and increasingly commuted into cash payments. Reformers like Turgot attempted to end the practice, and the broader system of feudal obligations was swept away during the revolutionary Night of August 4, 1789. By contrast, tailles were direct taxes (often on land or persons), gabelles were salt taxes, and levées referred to state levies—such as raising troops or collecting taxes—rather than mandatory labor.
