A normal office day produces a very specific cluster of grammar. You announce what you have to finish (muszę + infinitive), you fix when the meeting is (o + locative), and you ask what someone is doing after work (po + locative). This short dialogue between two colleagues, Marta and Tomek, packs all three patterns into the kind of half-formal, half-friendly talk Polish coworkers actually use. We present the whole exchange first, then take it line by line.
The dialogue
— Cześć Tomek, masz chwilę?
Hi Tomek, do you have a minute?
— Jasne, ale tylko chwilę. Muszę skończyć ten raport przed obiadem.
Sure, but only a minute. I have to finish this report before lunch.
— Spokojnie, szybko. O której jest spotkanie z klientem?
No worries, it'll be quick. What time is the meeting with the client?
— Spotkanie jest o trzeciej, w dużej sali konferencyjnej.
The meeting is at three, in the big conference room.
— Dobrze. Muszę jeszcze przygotować prezentację i wysłać kilka maili.
Good. I still have to prepare the presentation and send a few emails.
— A ja muszę porozmawiać z szefem o budżecie.
And I have to talk to the boss about the budget.
— Słuchaj, a co robisz po pracy? Idziemy na piwo?
Listen, what are you doing after work? Shall we go for a beer?
— Chętnie, ale po pracy mam jeszcze spotkanie. Może w piątek?
Gladly, but after work I still have a meeting. Maybe on Friday?
Line-by-line annotation
Masz chwilę? — the standard "got a sec?"
Masz chwilę? is the everyday way to interrupt a colleague. Literally "do you have a moment?", it drops the question particle czy the way spoken Polish almost always does in casual speech: rising intonation alone signals the question (see /grammar/polish/questions/yes-no-czy). Chwilę is the accusative of chwila ("moment"), the direct object of mieć ("to have"). Mind the spelling — chwilę ends in the nasal vowel ę (an e with the ogonek hook), not a plain e; dropping that diacritic is a classic beginner slip.
Muszę skończyć — obligation with musieć + infinitive
The engine of an office conversation is musieć, "to have to / must." Polish modality is built like English here: the conjugated modal carries the person, and the main verb stays in the infinitive.
Muszę skończyć ten raport.
I have to finish this report.
Muszę is the first-person singular of musieć; skończyć is the perfective infinitive ("to finish off, to complete"). The perfective is deliberate — Tomek means he must bring the report to completion, not merely work on it. Aspect choice after a modal is a real decision in Polish, covered at /grammar/polish/verbs-reference/musiec. The object ten raport is masculine inanimate, so its accusative looks identical to the nominative — a small mercy.
Muszę jeszcze przygotować prezentację i wysłać kilka maili.
I still have to prepare the presentation and send a few emails.
One muszę can govern two infinitives joined by i: przygotować and wysłać. Prezentację is the accusative of feminine prezentacja; kilka maili takes the genitive plural maili because the quantifier kilka ("a few") governs the genitive.
O której? and o trzeciej — clock time with o + locative
This is where English speakers stumble. To say at a clock time, Polish uses the preposition o plus the locative case — and the number behaves like an ordinal (a "th"-number), agreeing with an understood godzina ("hour"), which is feminine.
O której jest spotkanie?
(At) what time is the meeting?
Spotkanie jest o trzeciej.
The meeting is at three.
O której literally means "at which (hour)"; której is the locative of która. O trzeciej means "at the third (hour)" — trzeciej is the locative of the ordinal trzecia. So Polish does not say "at three" with the cardinal trzy; it says "at the third." The full system lives at /grammar/polish/cases/locative/about-o and the time-telling details at /grammar/polish/expressions/time-dates-appointments.
o budżecie — o + locative for the topic
Muszę porozmawiać z szefem o budżecie.
I have to talk to the boss about the budget.
Here o means "about." Budżecie is the locative of budżet (watch the ż with a dot and the soft cie ending — the t of budżet mutates to cie in the locative). Alongside it, z szefem ("with the boss") uses the instrumental with z for accompaniment: szefem is the instrumental of szef.
po pracy — po + locative for "after"
Co robisz po pracy?
What are you doing after work?
Po pracy mam jeszcze spotkanie.
After work I still have a meeting.
Po meaning "after (a point in time)" governs the locative. Pracy is the locative of feminine praca ("work"); it happens to look identical to the genitive, but the preposition po fixes it as locative. This is the same po you meet at /grammar/polish/cases/locative/prepositions-przy-po. Notice also Co robisz? — present tense covering a current/near-future plan. Polish has no separate continuous tense, so robisz covers both "do you do" and "are you doing" (see /grammar/polish/verbs/present/no-continuous-tense).
Idziemy na piwo? — a present-tense proposal
Idziemy na piwo?
Shall we go for a beer? / Are we going for a beer?
The first-person plural present idziemy ("we go / we're going") doubles as a soft proposal — extremely common in spoken Polish. Na piwo ("for a beer") uses na + accusative for the purpose/destination of the outing.
Common mistakes
❌ Spotkanie jest o trzy.
Incorrect — clock time needs the ordinal in the locative, not the cardinal.
✅ Spotkanie jest o trzeciej.
The meeting is at three.
❌ Muszę skończę ten raport.
Incorrect — the modal is followed by the infinitive, not a conjugated verb.
✅ Muszę skończyć ten raport.
I have to finish this report.
❌ Co robisz po praca?
Incorrect — po (after) governs the locative, not the nominative.
✅ Co robisz po pracy?
What are you doing after work?
❌ Muszę rozmawiać z szefem o budżet.
Incorrect — o (about) governs the locative, not the accusative.
✅ Muszę porozmawiać z szefem o budżecie.
I have to talk to the boss about the budget.
Key takeaways
- Masz chwilę? is the neutral, friendly "got a minute?"; the formal version is Ma pan/pani chwilę?
- Musieć takes a bare infinitive (muszę skończyć); the aspect of that infinitive still matters.
- Clock time uses o
- the locative of an ordinal (o trzeciej = "at the third hour").
- The same o
- locative also marks the topic of talk (o budżecie "about the budget").
- Po
- locative gives "after" in time (po pracy "after work").
