Translate ideas, not words.

• Polish is highly inflected, with seven cases and gendered nouns (including a masculine personal category). Restructure English sentences.
• Polish prefers verbs and active constructions; avoid English noun stacks and heavy nominalizations in new text.
• Re-express idioms by meaning: "it's a piece of cake" is "to betka" or "to pestka".
• Polish drops subject pronouns (Zapisaliśmy zmiany).

Grammar that trips translators.

• Plurals: one, few, many, and other categories (1 plik, 2 pliki, 5 plików, 1,5 pliku). See Unicode Messageformat.
• The vocative is used in direct address (Panie Janie, Aniu).
• Gendered verb forms in the past tense (zapisałem for a man, zapisałam for a woman) require knowing the speaker; UI text often avoids first-person past forms.
• Women's job titles (feminatywy such as programistka, dyrektorka) are increasingly used but still debated; follow the client's policy.

Register.

• Formal address uses third-person forms with Pan, Pani, or Państwo (Czy Pan chce zapisać?); informal address uses ty. UI and customer text commonly use Ty/ty or an impersonal style in consumer apps, and Pan/Pani/Państwo in banking, legal, and enterprise. In letters, Pan, Pani, Państwo, and Ty are capitalized.
• UI commands use the imperative (Zapisz) or the infinitive (Zapisz, Zapisać).

Orthography and typography.

• Quotation marks „…” with nested «…». Use a non-breaking space after single-letter words (i, a, o, u, w, z) to avoid orphan letters at line ends (sierotki).
• Numbers: decimal comma, non-breaking space for thousands; currency 12,50 zł with a non-breaking space; dates 17 października 2026 r.; 24-hour clock.
• Months, days, and nationalities are lowercase; titles use sentence case.

Common pitfalls

• Wrong number forms after numerals (5 plik).
• Missing the non-breaking space after single-letter words.
• Mixing ty and Pan/Pani.
• Wrong gender in first-person past verbs.
• Dropping Polish diacritics.
• Calques from English (aplikować for to apply to).
