Questions & Answers about Мы послушали музыку за час.
The English translation says "for an hour." Why does the Russian use за час instead of just час?
The English translation can be slightly misleading here. In Russian, за + Accusative (за час) shows the time it took to fully complete an action (often translated as "in an hour"). This implies finishing a specific task, like listening to a whole album. To simply say "we spent an hour listening" (ongoing duration), you would drop the за and use the bare Accusative час.
Why did we use the perfective verb послушали instead of the imperfective слушали?
The perfective verb послушали is used because the action was completed. Whenever you use за + a time word to show how long it took to finish something, you must use a perfective verb. If you wanted to focus on the ongoing process of listening without focusing on completion, you would use the imperfective слушали paired with the bare duration час.
Does the prefix по- in послушали add a specific meaning here?
Often, adding the prefix по- to a verb means doing an action for a limited time (like "listened for a bit"). However, because it is a perfective verb paired with за час, the sentence means we completed our specific block of listening within that one-hour timeframe.
Why is it музыку instead of the dictionary form музыка?
The noun музыка is the direct object here, meaning it is the thing receiving the action (the thing being listened to). Because of this, it must be in the Accusative case. For feminine nouns ending in -а, the ending changes to -у, making it музыку.
