Questions & Answers about Он пришёл и сделал всё по-вашему.
Why does по-вашему mean "your way" in this sentence?
The prefix по- combined with the dative ending -ему creates an adverb meaning "in the manner of" or "according to." Since it is built from ваш (your), по-вашему means "according to your way" or "in your style."
I've also seen по-вашему translated as "in your opinion." How do we know it means "your way" here?
Context is key! If it were a standalone introductory phrase like По-вашему, это хорошая идея?, it would mean "In your opinion, is this a good idea?". But here, it describes how he performed a specific action (сделал). When it modifies an action verb like this, it means the action was done "your way" or "according to your wishes."
Why is there a hyphen in по-вашему?
In Russian, adverbs formed with the prefix по- and ending in -ому, -ему, -ски, or -ки are always written with a hyphen. That is why you will also see hyphens in words like по-моему (in my opinion) and по-русски (in Russian).
Why are пришёл and сделал both in the perfective aspect?
Perfective verbs are used to show completed, one-time actions. When you string them together with "and" like this (пришёл и сделал), it shows a chronological sequence of events. First he arrived, and then he completed the task.
