Which term refers to the administration of day-to-day activities in a town?

The term that refers to the administration of day-to-day activities in a town is "Aedile." In ancient Rome, aediles were responsible for maintaining public buildings, organizing games and public festivals, and overseeing the markets. This role was crucial in ensuring that the urban environment functioned smoothly and that citizens’ needs were met. Aediles also played a significant part in enforcing local laws and regulations, effectively managing the various aspects of city life.

The other terms relate to different roles in Roman society. A lanista was a trainer or manager of gladiators, the editor was primarily associated with the organization of games or spectacles in the arena, and sparsiones referred to the practice of scattering (often related to the distribution of rewards or gifts during games). Each of these terms operates within a different context that does not pertain to the daily administrative functions of a town, making aedile the clearly accurate choice for this question.
