Questions & Answers about Ты можешь выучить это правило?
Since we are learning about perfective verbs, why is выучить not conjugated in the future tense here?
Here, выучить (to learn/memorize) stays in its dictionary form (the infinitive) because it comes right after the verb можешь (can). When you put two verbs together like this, only the first one changes to match the subject. You use the perfective verb выучить here because you are asking about the final result: successfully memorizing the rule to completion.
I know учить means to study or learn. How does the prefix вы- change it?
Adding the prefix вы- to учить creates its perfective partner. While учить focuses on the ongoing process of studying, the prefix вы- adds a sense of total completion. So, выучить specifically means to memorize something completely or learn it from start to finish.
Why does the sentence use это правило? Is it in the accusative case?
Yes! правило (rule) is the direct object receiving the action of being learned, so it must be in the accusative case. Because it ends in -о, it is a neuter noun. For inanimate neuter nouns, the accusative case looks exactly like the dictionary form. The word for 'this' must also match, taking the neuter accusative form это.
Why is there a soft sign (ь) at the end of можешь?
