Usage notesEdit
- The usage pattern is the same as that found with два (dva):
- о́ба (óba) and о́бе (óbe) in the nominative or accusative case govern the genitive singular of the noun. While the noun in a nominative construction is in the genitive singular following о́ба (óba) or о́бе (óbe), an intervening adjective will be in the genitive plural (if masculine or neuter) or nominative plural (if feminine):
- In the other cases, о́ба (óba) or о́бе (óbe) and any intervening adjective must all agree with the case of the noun:
- о́ба (óba) and о́бе (óbe) in the nominative or accusative case govern the genitive singular of the noun. While the noun in a nominative construction is in the genitive singular following о́ба (óba) or о́бе (óbe), an intervening adjective will be in the genitive plural (if masculine or neuter) or nominative plural (if feminine):
- The masculine genitive singular form обо́его (obójevo) is an anomaly that sees only limited use:
-
обо́его по́ла ― obójevo póla ― of both sexes
-
