Questions & Answers about W piątek o pierwszej jemy obiad.
Why doesn't the word piątek change its ending after the preposition w?
To say "on a day of the week", Polish uses w plus the Accusative case. Since piątek (Friday) is a masculine "inanimate" noun (meaning it's not a person or animal), its Accusative form is identical to its basic dictionary form. Therefore, no new ending is added.
Why do we use pierwszej instead of the regular number jeden (one) to say "at one o'clock"?
Polish tells time using ordinal numbers (first, second, third) rather than counting numbers (one, two, three). By using a form of pierwszy (first), you are literally saying "at the first [hour]", because the word godzina (hour) is understood but left out of the sentence.
Why does the word for "first" take the -ej ending to become pierwszej here?
When saying at a certain time, we use the preposition o followed by the Locative case. Because the hidden word godzina (hour) is feminine, we need the feminine Locative adjective ending, which is -ej. Therefore, the basic feminine form pierwsza (first) becomes pierwszej.
Is jemy a regular verb?
