Ordinal numbers (first, second, third, etc.) and usage - Polish Grammar

Ordinal numbers (first, second, third, etc.) — usage in Polish

Ordinals (Polish: liczebniki porządkowe) tell the order or position of items: first, second, third... In Polish, ordinals behave like adjectives: they agree with the noun they modify in gender (masculine/feminine/neuter), number (singular/plural) and case (nominative, genitive, etc.). This guide explains what ordinals mean, when to use them, how they are formed and declined, and common mistakes to avoid — with many examples.

What are ordinal numbers?

Ordinal numbers show position or rank in a sequence. Compare English: "first", "second", "third". In Polish: "pierwszy", "drugi", "trzeci". They can be used directly before a noun (as adjectives) or alone (as adjectives used as nouns):
[list]
[*]"pierwsza lekcja" (the first lesson)
[*]"Kto jest pierwszy? — Ja jestem pierwszy." (Who is first? — I'm first.)
[/list]

When do I use ordinal numbers in Polish?

Common uses:
[list]
[*]To show order or sequence: "pierwszy rozdział" (the first chapter), "druga próba" (the second attempt).
[*]For ranking/places: "zajął pierwsze miejsce" (he took first place).
[*]Dates and days in sentences: often "pierwszego maja" (on the first of May) when spoken; written dates commonly use numerals ("1 maja").
[*]Names of rulers and popes: "Jan III" = "Jan trzeci" (John the Third).
[*]Fixed expressions: "po raz pierwszy" (for the first time), "na pierwszym miejscu" (in the first place).
[*]When used as nouns: "Pierwsi wyszli z sali." (The first ones left the room.)
[/list]

How do I form ordinal numbers in Polish?

1) Basic ordinals you should learn by heart (1–20):
[list]
[*]1 — pierwszy (m), pierwsza (f), pierwsze (n) — first
[*]2 — drugi — second
[*]3 — trzeci — third
[*]4 — czwarty — fourth
[*]5 — piąty — fifth
[*]6 — szósty — sixth
[*]7 — siódmy — seventh
[*]8 — ósmy — eighth
[*]9 — dziewiąty — ninth
[*]10 — dziesiąty — tenth
[*]11 — jedenasty — eleventh
[*]12 — dwunasty — twelfth
[*]13 — trzynasty — thirteenth
[*]14 — czternasty — fourteenth
[*]15 — piętnasty — fifteenth
[*]16 — szesnasty — sixteenth
[*]17 — siedemnasty — seventeenth
[*]18 — osiemnasty — eighteenth
[*]19 — dziewiętnasty — nineteenth
[*]20 — dwudziesty — twentieth
[/list]

2) Tens (regular pattern for 30, 40, ...):
[list]
[*]30 — trzydziesty (thirtieth)
[*]40 — czterdziesty (fortieth)
[*]50 — pięćdziesiąty (fiftieth)
[*]60 — sześćdziesiąty (sixtieth)
[*]70 — siedemdziesiąty (seventieth)
[*]80 — osiemdziesiąty (eightieth)
[*]90 — dziewięćdziesiąty (ninetieth)
[*]100 — setny (one-hundredth)
[/list]

3) Compound ordinals (21, 32, 47, etc.)

- For numbers from 21 to 99 you normally combine the tens-ordinal with the ones-ordinal: tens + units. Example:
[list]
[*]21 — dwudziesty pierwszy (dwudziesta pierwsza for feminine nouns; dwudzieste pierwsze for neuter)
[*]32 — trzydziesty drugi
[*]47 — czterdziesty siódmy
[/list]

- Important: in compound ordinals each element declines and must agree with the noun. Example:
[list]
[*]Nominative: "Dwudziesty pierwszy dzień" (the twenty-first day)
[*]Feminine: "Dwudziesta pierwsza rocznica" (the twenty-first anniversary)
[*]Genitive (date): "dwudziestego pierwszego grudnia" (on the 21st of December — both words are in genitive)
[/list]

4) Numbers above 100

- 100th is "setny".
- For most compound numbers above 100, speakers use the cardinal for hundreds/thousands and make the final part ordinal. Examples:
[list]
[*]101 — sto pierwszy (one hundred and first)
[*]112 — sto dwunasty (one hundred and twelfth)
[*]221 — dwieście dwudziesty pierwszy (two hundred twenty-first)
[*]234 — dwieście trzydziesty czwarty (two hundred thirty-fourth)
[/list]

- There are also special ordinal words for round hundreds and thousands (100 — setny; 200 — dwusetny; 1000 — tysięczny), but for most compound numbers (e.g. 201, 345) the pattern above is used.

How do ordinal numbers agree with gender, number and case?

Because ordinals are adjectives, they change form to match the noun (gender: masculine/feminine/neuter; number: singular/plural; case: nominative/genitive/dative/accusative/instrumental/locative).

Examples in sentences (showing different cases):
[list]
[*]Nominative: "To jest moja pierwsza książka." (This is my first book.)
[*]Genitive: "Nie pamiętam pierwszego dnia." (I don't remember the first day.)
[*]Dative: "Podziękowałem pierwszemu wolontariuszowi." (I thanked the first volunteer.)
[*]Accusative (animate): "Widzę pierwszego zawodnika." (I see the first contestant.)
[*]Accusative (inanimate): "Obejrzałem pierwszy film." (I watched the first film.)
[*]Instrumental: "Jesteśmy pierwszym pokoleniem." (We are the first generation.)
[*]Locative: "Mówi się o pierwszym rozdziale." (People talk about the first chapter.)
[*]Plural (masc. personal): "Pierwsi uczniowie przyszli." (The first students arrived.)
[*]Plural (non-personal): "Pierwsze pytania były proste." (The first questions were easy.)
[/list]

How are ordinals used with dates and months?

- Written forms: Poles often write the numeral + month in the genitive: "1 maja 2020" (1 May 2020).
- Spoken/full-sentence forms: Ordinals in genitive are common: "pierwszego maja 2020 roku". Example: "Dzień Pracy obchodzimy pierwszego maja." (We celebrate Labor Day on the first of May.)

Note: Many contexts allow either the numeric short form (1 maja) or the spoken genitive ordinal (pierwszego maja); when the date is inside a full sentence the genitive ordinal is very common.

How do I write and abbreviate ordinals?

- The standard abbreviation in Polish for ordinals is a period after the numeral: "1.", "2.", "3.". Example: "zajął 1. miejsce" (he took 1st place).
- Informal written shortcuts exist ("1-szy", "2-ga"), but avoid them in formal writing.

Common mistakes to avoid

[list]
[*]Wrong gender: writing "pierwszy książka" — correct: "pierwsza książka".
[*]Using cardinals instead of ordinals (or vice versa): "on jest jeden" vs "on jest pierwszy" ("jeden" = the number one; "pierwszy" = first in order).
[*]Not declining compound ordinals correctly: when the phrase needs genitive, decline both words: "dwudziestego pierwszego grudnia", not "dwudziesty pierwszy grudnia".
[*]Overusing informal abbreviations like "1-szy" in formal texts.
[*]Confusing written short dates ("1 maja") with the spoken genitive form ("pierwszego maja"). When used in a sentence, the genitive ordinal is common.
