Ordinal Numbers
Learn how to form and use Polish ordinal numbers (first, second, third) by treating them as adjectives that must agree in gender, number, and case with the noun they describe.
Learning goals
By the end of this lesson, you will be able to:
- Understand that ordinal numbers in Polish function as adjectives.
- Form ordinal numbers from 1 to 10 and beyond, including compound numbers.
- Apply correct gender, number, and case agreement to ordinal numbers based on the nouns they describe.
- Correctly write ordinal numbers using the required "dot" notation.
- Understand their usage in dates, floors, rankings, and history.
Grammar rules
Ordinal numbers indicate the position or order of something (e.g., first, second, third), unlike cardinal numbers which indicate quantity (one, two, three).
The Golden Rule: In Polish, ordinal numbers act exactly like adjectives. Because of this, they must agree with the noun they modify in three ways:
- Gender: Masculine (pierwszy), Feminine (pierwsza), or Neuter (pierwsze).
- Number: Singular or Plural (pierwsi vs. pierwsze).
- Case: They decline through all 7 Polish cases (Nominative, Genitive, etc.).
Base Ordinal Numbers (1–10)
These are the foundations you need to memorize.
| Number | Masculine | Feminine | Neuter |
|---|---|---|---|
| 1st | pierwszy | pierwsza | pierwsze |
| 2nd | drugi | druga | drugie |
| 3rd | trzeci | trzecia | trzecie |
| 4th | czwarty | czwarta | czwarte |
| 5th | piąty | piąta | piąte |
| 6th | szósty | szósta | szóste |
| 7th | siódmy | siódma | siódme |
| 8th | ósmy | ósma | ósme |
| 9th | dziewiąty | dziewiąta | dziewiąte |
| 10th | dziesiąty | dziesiąta | dziesiąte |
Forming Larger Numbers
- 11th–19th: Add the suffix -nasty to the base (e.g., 11th = jedenasty). Note: 12th is dwunasty.
- Tens (20th, 30th, 40th): These end in -dziesty or -dziesiąty (e.g., 20th = dwudziesty, 30th = trzydziesty, 50th = pięćdziesiąty).
- Compound Numbers: Only the tens and units take the ordinal form. Hundreds and thousands remain as cardinal numbers (e.g., 145th = sto czterdziesty piąty).
Declension / Conjugation patterns
Ordinal numbers have distinct forms for Plural Masculine Personal vs. Non-Personal groups, just like adjectives:
- Masculine Personal: Used for groups containing at least one male (e.g., pierwsi goście - first guests).
- Non-Personal: Used for everything else (e.g., pierwsze samochody - first cars).
Examples
| Polish | English | Notes |
|---|---|---|
| Dzisiaj jest szósty marca. | Today is the 6th of March. | Nominative case. |
| Moje urodziny są dwudziestego pierwszego lipca. | My birthday is on the 21st of July. | Genitive case (used for dates). |
| Mieszkam na trzecim piętrze. | I live on the third floor. | Locative case (due to na). |
| Żyjemy w dwudziestym pierwszym wieku. | We live in the 21st century. | Locative case (due to w). |
| On zajął pierwsze miejsce. | He took first place. | Accusative case. |
| Moja córka chodzi do ósmej klasy. | My daughter goes to the 8th grade. | Genitive case (due to do). |
Common mistakes
- Missing the dot: In writing, you must use a period after a digit to mark an ordinal number (e.g., "3. piętro"). Writing "3 piętro" implies the quantity "three floors".
- Declining the whole number: When writing years or large numbers (e.g., 1999th), do not put every part into an ordinal form. Only the last two parts change.
- Wrong case for dates: Remember that "on [a date]" requires the Genitive case.
- Incorrect Month case: When naming dates, the month is almost always in the Genitive case (the second of February).
When writing out dates like "1st of May", remember that the Polish structure is different. Even if you are saying "Today is the 1st", the month must follow in the Genitive case because you are saying "the first [day] OF May" (pierwszy maja).
Quick recap
- Ordinal numbers are adjectives and must match the noun's gender, number, and case.
- Memorize 1–10; use suffixes for higher numbers.
- In compound numbers (e.g., 145th), only the tens and units are ordinal.
- Always include the dot after a digit (e.g., 1.) when writing ordinals.
- Use the Genitive case for specific dates and the Locative case for locations like floors or centuries.
