Polski — the vocative case
Polish keeps a separate vocative case used only to address someone directly. You hear it in Panie profesorze!, Aniu! and mamo! — though in casual speech it is often replaced by the nominative.
How it works
Masculine nouns take -e (with a consonant shift: profesor → profesorze) or -u (syn → synu); feminine nouns take -o (mama → mamo) or -u for soft stems and diminutives (Ania → Aniu); neuter nouns are identical to the nominative (dziecko → dziecko). Titles combine: Panie profesorze!
Examples
| Nominative | Vocative | Meaning / ending |
|---|---|---|
| pan | panie | sir, man (m., -e) |
| profesor | profesorze | professor (m., -e) |
| syn | synu | son (m., -u) |
| Bóg | Boże | God (m., -e, ó→o) |
| mama | mamo | mum (f., -o) |
| Ania | Aniu | Ania (f. diminutive, -u) |
| pani | pani | madam (f., unchanged) |
| dziecko | dziecko | child (n., = nominative) |
Good to know
In everyday speech the vocative is often dropped in favour of the nominative — people say Mama! rather than Mamo!, and Ania! rather than Aniu!. It stays firmly alive in polite address (Panie profesorze!, Proszę pani!) and in set phrases, so learners should still recognise and use it there.
