suppletivo
Suppletivo refers to something that supplements or completes something else, often filling in a gap or providing additional support. The term is frequently used in educational contexts, particularly in European countries, to describe a supplementary curriculum or a program designed to help students catch up on missed material or enhance their existing knowledge. These programs can take various forms, such as extra tutoring, specialized workshops, or additional courses.
