Questions & Answers about Её настойчивость всех удивляет.
Since this lesson is about всё-таки (nevertheless), how would I add it to this sentence to say her persistence surprises everyone nevertheless?
You could place it right after the subject or before the verb. A very natural spot would be Её настойчивость всё-таки всех удивляет (or you could use всё же). This implies that despite some prior context, such as her failing many times before, her persistence still manages to surprise everyone.
Why is всех placed before the verb удивляет instead of after it?
In Russian, placing the object before the verb is common, especially with short pronouns like всех (everyone) or меня (me). It makes the sentence flow more naturally and puts a slight focus on the action itself. Saying Её настойчивость удивляет всех is also perfectly correct but places slightly more emphatic stress on the word for everyone at the end of the sentence.
Is всех in the genitive or accusative case here?
It is in the accusative case. The verb удивлять (to surprise) requires a direct object in the accusative case because you are surprising someone. Because the pronoun все (everyone) is animate, its accusative form matches its genitive form, making it всех.
Why use the imperfective verb удивляет instead of a perfective form?
