problemojn

Problemojn is the Esperanto plural accusative form of problemo, meaning “problems.” In Esperanto, nouns end in -o for the basic form, -j marks the plural, and -n marks the accusative case. Therefore problemojn denotes several problems that are the direct object of a verb or of a prepositional phrase.

The nominative plural of the word is problemoj, which is used when the problems are the subject of a sentence. For example: Problemoj estas oftaj en matematiko. The accusative form appears in sentences like Mi havas problemojn or Mi solvas problemojn, where the problems are what is being possessed or solved.

Common examples include:

- Mi havas problemojn. (I have problems.)

- Mi solvas problemojn. (I solve problems.)

- La instruisto donis kelkajn problemojn al la studentoj. (The teacher gave several problems to the students.)

Etymology and form: problemo derives from European languages such as French or Italian (problème, problema) and was adopted into Esperanto with its regular noun endings. The -n ending is added to indicate the accusative, while -j marks plurality, yielding problemojn for “the problems” in the object position.

Usage notes: Problemojn can refer to mathematical exercises as well as to general difficulties or issues in daily life, science, or policy. When speaking about the problems as the subject, use problemoj; when they serve as the direct object, use problemojn.

In summary, problemojn is the standard Esperanto way to say “problems” as the direct object in a sentence, reflecting Esperanto’s regular system of noun endings and case marking.
