Breakdown of Почему бы нам не зайти в библиотеку после работы?
Questions & Answers about Почему бы нам не зайти в библиотеку после работы?
In this pattern, почему бы… не + infinitive is an idiomatic way to make a friendly suggestion: “Why don’t we…?” / “How about we…?”
- почему on its own is “why?”
- бы is a particle that adds a hypothetical/softened, “it would be nice if…” tone (similar in function to the conditional would in English).
So почему бы нам не зайти… is not a real request for a reason; it’s a suggestion.
In Russian, the suggestion construction requires не: почему бы (кому) не + infinitive. It looks like a negative, but it functions like English “Why don’t we…?”—which also contains “don’t” even though you’re proposing doing something.
Because this construction uses the dative to mark “to/for whom” the suggestion applies:
- почему бы нам не… = “why wouldn’t it be (good) for us to…?” → “why don’t we…?” Common variants:
- почему бы тебе не… (to you) = “why don’t you…?”
- почему бы им не… (to them) = “why don’t they…?”
Yes. Почему бы не зайти в библиотеку после работы? is natural and means “Why not stop by the library after work?”
Adding нам just makes it explicitly “we/us.”
зайти is perfective and commonly used for a single, complete “drop in/stop by” action—exactly what a one-time suggestion usually implies.
- Почему бы нам не зайти…? = “Why don’t we stop by (once)…?” If you used imperfective заходить, it would more often suggest a repeated/habitual idea or focus on the process:
- Почему бы нам не заходить туда после работы? = “Why don’t we drop in there after work (regularly)?”
зайти means “to drop in/stop by (briefly),” often on the way somewhere else or as an extra stop. It implies a short visit.
- пойти в библиотеку = “to go to the library” (as the main destination)
- зайти в библиотеку = “to pop into the library” (a quick stop)
Because motion to/into a place uses в + accusative:
- в библиотеку (accusative) = “to the library / into the library” Location in a place uses в + prepositional:
- в библиотеке (prepositional) = “in the library”
The preposition после requires the genitive case:
- после работы = “after work” (genitive of работа) Same pattern:
- после урока (after the lesson)
- после встречи (after the meeting)
By itself, после работы is ambiguous and can mean either, but in a specific suggestion like this, it normally means “after work (today/this time),” depending on context. If you want to force “today,” you can say:
- после работы сегодня = “after work today”
The given order is very natural: Почему бы нам не зайти в библиотеку после работы? Some movement is possible for emphasis:
- Почему бы нам после работы не зайти в библиотеку? (emphasizes “after work”)
- После работы почему бы нам не зайти в библиотеку? (sets the time first) But you generally keep почему бы + (dative) + не + infinitive together.
It’s neutral-to-friendly and quite polite for a suggestion. It’s softer than an imperative like Давай зайдём… (“Let’s stop by…”), and it doesn’t pressure the listener. It works well with friends, coworkers, and in many everyday situations.
