Questions & Answers about Я никогда ничего не понимаю. Что за бред?
How does что за work here, and why is бред in the nominative case?
The phrase что за is a fixed exclamatory structure used to ask what kind of a thing something is, or to express surprise and indignation. Even though it contains the preposition за which normally demands the accusative or instrumental case, the fixed idiom что за always takes the nominative case. Therefore, бред remains in its basic dictionary form.
I originally learned that бред means delirium. Is it always used to mean nonsense?
In medical contexts, бред does mean delirium. However, in everyday colloquial Russian, it is extremely common to use it metaphorically to mean nonsense, rubbish, or absurd talk. Paired with что за, it perfectly captures the frustrated feeling of asking what kind of nonsense something is.
Why are there three negative words (никогда, ничего, не) in the first sentence?
Russian requires multiple negation. Unlike English, which avoids double negatives, Russian demands that if you use negative pronouns like ничего or negative adverbs like никогда, you must still negate the main verb with не. The sentence literally translates to 'I never nothing not understand.'
Could I change the word order to Я не понимаю ничего никогда?
