Reppua

Reppua is the partitive singular form of the Finnish noun reppu, which means backpack. A reppu is a bag worn on the back, commonly used for school, travel, or outdoor activities. The term is widely used in everyday Finnish language, and its inflection follows standard Finnish noun patterns.

In Finnish grammar, reppua is used as the direct object in contexts where the object is indefinite, part of a noncompleted action, or described after negation. For example: "Tarvitsen reppua" means "I need a backpack," and "En näe reppua" means "I do not see a backpack." The plural form reppuja is used for "backpacks" in similar contexts, as in "Ostin kaksi reppuja" (I bought two backpacks). The base forms of reppu include nominative reppu and genitive repun; the partitive plural is reppuja.

Notes on usage: Finnish often selects the partitive case for direct objects under negation or when the quantity is indefinite or partial. While reppua specifically marks the partitive singular, different sentences may use other cases (such as repun or reppu) depending on meaning, definiteness, and syntactic role. In everyday speech, the choice between reppua and other object forms reflects nuance rather than a fixed rule.
