corsi

Corsi is the plural form of the Italian noun corso and covers several related meanings that share the idea of a path, route, or sequence. In everyday Italian it is most often associated with educational programs, but it also appears in geography, hydrology, and urban usage.

In education, i corsi refer to courses or classes, such as i corsi universitari, corsi di lingua, or corsi di formazione. They can denote a structured program of study or a set of instructional sessions within a curriculum. The singular form corso is used for one class or course, while corsi denotes multiple offerings.

In geography and hydrology, i corsi d'acqua are watercourses—the paths followed by rivers, streams, or other bodies of water. The phrase il corso di un fiume describes the river’s course from source to mouth. The sense extends to any defined channel or conduit through which something moves or is directed.

In urban and cultural usage, corso can also indicate a main street or promenade, especially in Italian towns. When used in the plural as i corsi, it can refer to several such streets, often seen in place names like Corso Vittorio Emanuele.

The word ultimately derives from Latin cursus, meaning running, path, or course. Distinguishing from corse, which in Italian means races or runs, corsi emphasizes a planned path or sequence rather than a single athletic event.
