не можна не + Infinitive
Inevitable Acknowledgement with Не Можна Не
The pattern не можна не + інфінітив (cannot but / must) is a sophisticated way to say that an action is unavoidable, logically necessary, or morally obligatory.
How It Works
This construction is common in formal Ukrainian discourse, though it carries specific stylistic nuances.
1. Structure and Logic:
It consists of the modal predicative не можна (it is not possible/allowed) followed by the negative particle не and an infinitive. Unlike simple negative intensification, these two negatives logically cancel each other out to create a positive meaning: 'one cannot not' equals 'one must.'
2. Aspect Usage:
- Use a perfective infinitive for specific, one-time inevitable results (e.g., не можна не помітити - one cannot fail to notice).
- Use an imperfective infinitive for ongoing states or feelings (e.g., не можна не захоплюватися - one cannot but admire).
3. Stylistic Note:
While widely used in journalism and academic writing, many modern linguists criticize this pattern as a calque (loan translation) from Russian. It can sometimes sound bureaucratic. To sound more natural or to avoid this 'Russianism,' you can become confident with alternatives like варто, слід, or the more native-sounding неможливо не.

Common Mistakes
Writing 'не можна' as a single word.
Неможна не визнати цей факт.Не можна не визнати цей факт.In modern Ukrainian, 'не можна' is always written as two separate words, unlike 'неможливо' which is one word.
Dropping the second 'не'.
Different MeaningНе можна сміятися.Не можна не сміятися.'Не можна сміятися' is correct, but it means 'it is forbidden to laugh'. You need both particles for the 'cannot but' meaning: 'не можна не сміятися' (one cannot help laughing).
How It Connects
Learn This First
To learn the emphatic 'не можна не' construction, you first need to understand how basic negation works in Ukrainian and how modal words like 'можна' (one can) or 'варто' (it is worth) function as predicates followed by an infinitive. This pattern uses a double negative to create a strong positive assertion.
