Accusative Duration
In Polish, duration is expressed by putting the time unit in the accusative case without any preposition. It answers the question Jak długo? (How long?).
How It Works
The Accusative Duration (biernik trwania) is the standard way to indicate the length of time an activity or state persists.
1. Morphology:
The time noun must follow accusative declension rules:
- Feminine: Nouns ending in -a change to -ę (e.g., godzinę, minutę). Note that feminine adjectives take the -ą ending (e.g., całą godzinę), and feminine nouns ending in a consonant (like noc) remain unchanged.
- Masculine Inanimate: Usually looks like the nominative (e.g., rok, dzień, miesiąc).
- Neuter: Just like masculine inanimate nouns, neuter nouns look identical to the nominative in the accusative singular (e.g., całe popołudnie, stulecie).
- Number 1: Takes the standard accusative singular (e.g., jedną godzinę, jeden rok).
- Plural: Follows accusative plural rules for numbers 2-4 (e.g., dwie godziny). However, for numbers 5 and above, the number itself remains in the accusative (which looks identical to the nominative), while the noun requires the genitive plural (e.g., pięć lat).
2. Usage with Verbs:
It is most commonly used with imperfective verbs because they describe ongoing actions. However, it is also used with specific perfective verbs:
- Prefix po-: Delimitative verbs (e.g., posiedzieć - to sit for a while, pobyć) indicate an action lasting for a limited time.
- Prefix prze-: Perdurative verbs (e.g., przepracować - to work through, przespać - to sleep through) indicate that the action filled the entire duration mentioned.
3. Bare Accusative vs. Przez:
Learners often use przez + accusative to mimic the English 'for'. While the bare accusative is the neutral choice, przez is used to emphasize continuity. It suggests the action occurred without interruption throughout the entire span of time.
4. Negation:
Unlike direct objects which change to the genitive case under negation, time expressions of duration usually remain in the accusative even when the verb is negated. However, the genitive can be used to mean 'not even [a unit of time]' (e.g., Nie spałem (ani) godziny - I didn't sleep (even) an hour).
5. Other Accusative Time Expressions:
Do not confuse bare accusative duration with other time expressions using prepositions:
- Na + accusative: Used for intended or scheduled duration (e.g., Jadę do Polski na tydzień - I am going to Poland for a week).
- Za + accusative: Used for a future point in time (e.g., Zadzwonię za godzinę - I will call in an hour).
- W + accusative: Commonly used for days of the week (e.g., w środę - on Wednesday).
Examples (6)
- Czekałem na ciebie całą godzinę.
I waited for you for a whole hour.
Word by Word: I-waited for you whole hour.
The feminine noun 'godzina' changes to 'godzinę' in the accusative to show duration.
- Mieszkałem w Krakowie jeden rok.
I lived in Krakow for one year.
Word by Word: I-lived in Krakow one year.
The masculine inanimate noun 'rok' stays the same in the accusative.
- Nie spałam całą noc.
I didn't sleep all night.
Word by Word: Not I-slept whole night.
Even though the verb is negated, 'całą noc' remains in the accusative case.
- Posiedzieliśmy chwilę w parku.
We sat for a while in the park.
Word by Word: We-sat-for-a-while moment in park.
The perfective verb 'posiedzieć' (prefix po-) uses the accusative 'chwilę' to show a limited duration.
- Przepracowałam w tej firmie cały rok.
I worked in this company for a whole year.
Word by Word: I-worked-through in this company whole year.
The perfective prefix 'prze-' indicates that the action spanned the entire duration of the year.
- Czytałem tę książkę przez całą noc.
I was reading this book throughout the entire night.
Word by Word: I-read this book through whole night.
Using 'przez' emphasizes that the action was continuous and uninterrupted for the whole period.
Common Mistakes
Using 'dla' to express duration.
Czekałem dla godziny.Czekałem godzinę.'Dla' is used for beneficiaries (e.g., 'for you'), never for time. Use the bare accusative instead.
Forgetting the -ę ending for feminine time words.
Czekałem cała godzina.Czekałem całą godzinę.Feminine nouns and adjectives must take the accusative endings (-ę / -ą) when expressing duration.
Believing the genitive is wrong for a duration after a negated verb.
Different MeaningNie spałem całej nocy.Nie spałem całą noc.Both are grammatical. 'Nie spałem całej nocy' follows the genitive-of-negation pattern, while 'Nie spałem całą noc' with the accusative is the usual choice for 'I stayed awake all night long'.
