g / dz
G and Dz Alternation
In Polish, the letter g often changes to dz when followed by certain endings like -e or -i. This happens in feminine dative/locative cases and masculine personal plurals.
How It Works
The g → dz alternation is a systematic phonological shift. It is triggered by 'softening' vowels that follow the stem.
1. Feminine Nouns (Singular)
When a feminine noun ends in -ga, the g changes to dz before the Locative or Dative ending -e.
- noga (leg) → nodze
- droga (road) → drodze
2. Masculine Personal Nouns (Plural)
In the Masculine-Personal Plural, the ending is often -i. Because of Polish spelling rules, dz + i is written as dzy.
- kolega (colleague) → koledzy
- biolog (biologist) → biolodzy
3. Adjectives (Masculine Personal Plural)
Similarly, adjectives describing groups of men (or mixed groups) undergo this change before the plural ending.
- drogi (dear/expensive) → drodzy
- ubogi (poor) → ubodzy
Note: Do not confuse this with g → ż, which happens in verbs (mogę/możesz) or the Vocative (Bóg/Boże).
Examples (4)
- Mieszkam w Pradze.
I live in Prague.
Word by Word: I live in Prague.
The city 'Praga' (feminine) changes 'g' to 'dz' in the locative case after the preposition 'w'.
- Moi koledzy są tutaj.
My colleagues are here.
Word by Word: My colleagues are here.
The noun 'kolega' (masculine personal) changes 'g' to 'dz' in the nominative plural.
- Drodzy państwo, zapraszam!
Dear ladies and gentlemen, I invite you!
Word by Word: Dear [plural-polite], I invite!
The adjective 'drogi' (dear) changes to 'drodzy' to agree with the masculine-personal plural 'państwo'.
- Daję to mojej papudze.
I am giving it to my parrot.
Word by Word: I give it to my parrot.
The feminine noun 'papuga' changes to 'papudze' in the dative case (indirect object).
Common Mistakes
Applying the change to masculine inanimate nouns.
Widzę pociądzy.Widzę pociągi.The g → dz change in the plural ONLY applies to 'masculine personal' nouns (humans). For inanimate objects like 'pociąg' (train), the plural is 'pociągi'.
Using the wrong locative ending for feminine nouns.
Jestem w drogu.Jestem w drodze.Feminine nouns ending in -ga must use the -e ending in the locative, which triggers the g → dz shift. The -u ending is for masculine/neuter nouns.
