Breakdown of Без отрицания это предложение звучит странно.
Questions & Answers about Без отрицания это предложение звучит странно.
Because the preposition без always takes the genitive.
So:
- без
- genitive = without ...
- dictionary form: отрицание
- genitive singular: отрицания
Other examples:
- без сахара = without sugar
- без проблем = without problems
- без ошибки = without a mistake
So без отрицания is grammatically the normal pattern.
Here отрицание means negation in a grammatical or logical sense, not just emotional denial.
In Russian, отрицание can mean:
- denial
- refusal
- negation
But in this sentence, it most naturally means something like a negative element in the sentence, for example не or another form of negation.
So the idea is that if you remove the negation, the sentence sounds odd.
