arborelui

Arborelui is a Romanian noun form derived from arbore, meaning tree. It is the genitive and dative singular form, used to express possession or to indicate the indirect object in a sentence. For example, in frunzele arborelui, the leaves belong to the tree and arborelui marks the relationship as “of the tree.”

The base noun arbore is masculine. The definite singular form is arborele, used when the tree is the subject or object already specified as a particular tree. The genitive/dative singular arborelui is used after prepositions or with possessive constructions to show relation to the tree, such as frunzele arborelui (the leaves of the tree) or ramurile arborelui (the branches of the tree).

Plural forms follow Romanian declension patterns. Indefinite nominative/accusative plural is arbori, while definite nominative/accusative plural is arborii. Genitive/dative plural is arborilor, and the definite genitive/dative plural is arborilor as well. These forms allow expressing relations to multiple trees, for example frunzele arborilor (the leaves of the trees).

Etymology and usage notes: arbore comes from Latin arbor, arboris, reflecting the shared Romance tradition. In Romanian, arborelui as a genitive/dative singular appears frequently in descriptive phrases, scientific terminology, and literature to denote ownership or association with a specific tree. Like many Romanian nouns, its exact form changes with number and definiteness, but arborelui remains the standard genitive/dative singular form.
