Questions & Answers about Nie rozlewaj herbaty, proszę.
It’s informal, addressed to one person you’re on a first‑name basis with (the implicit subject is ty). For a polite/formal request to a stranger or service worker, use:
- Niech pan/pani nie rozlewa herbaty, proszę.
- or: Proszę nie rozlewać herbaty.
Because of the “genitive of negation.” A direct object that would be in the accusative in an affirmative sentence often switches to genitive under negation.
- Affirmative: (Nie) rozlej/rozlewaj herbatę. (accusative)
- Negative: Nie rozlewaj herbaty. (genitive)
Here, herbata (tea) → herbaty in the genitive singular.
Aspect:
- Nie rozlewaj uses the imperfective verb rozlewać. It blocks the ongoing/activity of spilling or spilling in general (e.g., while someone is handling a cup).
- Nie rozlej uses the perfective rozlać. It blocks a single, completed result: “Don’t end up spilling (this once).”
Both are correct; Nie rozlewaj is the go‑to warning while someone is pouring/handling a drink.
