Questions & Answers about Бутылка, которую я бросил в озеро, уже всплыла.
How does the prefix вс- change the meaning of the verb in всплыла?
The base verb here is плыть, which is the one-way verb of motion for "to swim" or "to float". The prefix вс- (a variation of вз-) adds the meaning of upward motion. Together, всплыть means "to float up" or "to surface."
Why does всплыла use the prefix вс- instead of вз-?
The upward prefix вз- changes its spelling to вс- whenever it is attached to a word that starts with a voiceless consonant (such as п, т, к, с, or х). Since the base verb плыть starts with the voiceless sound п, the prefix becomes вс- so it is easier to pronounce.
Why is the word for "that" (которую) in the accusative case, when it refers to the subject (бутылка)?
The word который takes its gender and number from the noun it refers back to (since бутылка is feminine singular, we use a feminine singular form). However, its case is determined by its job inside its own clause. In the phrase "that I threw" (которую я бросил), "I" is the subject doing the throwing, and "that" (the bottle) is the direct object receiving the action. Therefore, it takes the accusative case: которую.
Why do we say в озеро (accusative) instead of в озере (prepositional)?
