Questions & Answers about Ósmy rachunek jest wysoki.

Why is ósmy in that form?

Ósmy is the ordinal number meaning eighth, and in Polish ordinal numbers behave like adjectives. That means they have to agree with the noun they describe in:

• gender
• number
• case

Here, the noun is rachunek, which is masculine singular nominative, so the matching form is ósmy.

If the noun were feminine, you would get ósma. For example:

• ósma strona = the eighth page

Why are both ósmy and wysoki masculine singular?

Because both words agree with rachunek.

• rachunek is masculine
• it is singular
• in this sentence it is in the nominative

So:

• ósmy rachunek = masculine singular nominative
• rachunek jest wysoki = wysoki also matches the same noun

This is very normal in Polish: adjectives usually match the noun they refer to.
