Questions & Answers about Ей не нужно суетиться, чтобы всё успеть.
Why is суетиться (to fuss) in the imperfective aspect here?
In Russian, when you state that an action is unnecessary using не нужно or не надо, you use the imperfective aspect. This shows that the general action of "fussing" shouldn't happen at all, regardless of whether it would be completed.
Why does the sentence start with Ей (to her) instead of Она (she)?
The word нужно acts like an impersonal "it is necessary." The person who experiences this need (or lack of need) must be in the Dative case, so Она becomes Ей. Literally, it reads "To her it is not necessary..."
Since суетиться is imperfective, why is успеть (to manage) perfective?
The rule forcing the imperfective only applies to the verb directly attached to не нужно. The second verb, успеть, describes the goal she wants to successfully achieve (getting everything done). Because it focuses on a successful result rather than a process, it takes the perfective aspect.
How does чтобы work in this sentence?
When followed by an infinitive, чтобы means "in order to." In English, we often shorten this to just "to" (like "She doesn't need to fuss to manage everything"), but Russian strictly requires чтобы here to show the purpose.
Does всё успеть literally mean "to manage everything"?
