Problemoj

Problemoj is the plural form of the Esperanto noun problemo. In Esperanto, problemo means a problem, a question to be solved, or a difficulty. It can refer to mathematical exercises, practical issues, or philosophical inquiries. The term is borrowed from Latin problemа via French problème and Greek problema, and it conforms to Esperanto morphology: nouns end in -o, and plurals in -oj.

Etymology and morphology: The Esperanto word follows the common pattern for nouns, with the plural marker -j added to form problemoj. This reflects Esperanto’s goal of regular inflection and cross-language recognizability. The root problemo is related to the idea of something to be considered or solved, which is reflected in its usage across domains.

Usage and contexts: In mathematics and science, a problemo is typically a task or question designed to be solved; one says solvi la problemon (to solve the problem). In everyday language, it can denote any difficulty or issue: "ni havas problemojn" (we have problems). In education and media, problemoj are discussed as items within problem sets, research questions, or public-policy debates.

Examples: La problemo estas malfacila, sed ni trovos solvon. Ni havas plurajn problemojn hodiaŭ. These usages illustrate the range from formal exercises to real-world difficulties, all expressed with the same plural form.
