Yhdeksäs

Yhdeksäs is an ordinal numeral in Finnish meaning “the ninth.” It is the ordinal form derived from the cardinal number yhdeksän (nine) and is used to express order or position within a sequence, such as dates, floors, months, or ranks.

In Finnish, ordinals like yhdeksäs are used before a noun to indicate order and are declined to agree with the noun in number and case. In the common nominative singular, you typically see expressions such as yhdeksäs kerros (the ninth floor) or yhdeksäs kuukausi (the ninth month). The form changes with different cases just as adjectives do in Finnish, so the ending may vary depending on grammatical role.

Common uses include describing positions in lists, stages in processes, or calendar-related references. For example, saying someone finished in the ninth spot or that something is placed on the ninth day of a month are typical contexts for yhdeksäs. It is typical to pair ordinal yhdeksäs with a noun to specify what is being ordered or dated.

Etymologically, yhdeksäs comes from the number yhdeksän plus the Finnish ordinal suffix pattern, aligning with other ordinals such as kahdeksas (eight) and kymmenes (tenth). Related forms include the base yhdeksän (nine) and other ordinals like kahdeksas and kymmenes. Finnish ordinals generally follow the same grammatical rules as adjectives, affecting agreement with nouns and case endings.
