Questions & Answers about Громкий шум обычно прерывает цикл сна.
Why does the word for sleep change from сон to сна here?
It is in the Genitive case to express the cycle of sleep. The noun сон (sleep) contains a fleeting vowel (or mobile vowel). When a case ending is added, the о drops out, making the Genitive form сна instead of retaining the original vowel.
Is цикл in the Nominative case here?
No, it is the direct object of the verb прерывает (interrupts), so it is in the Accusative case. Because цикл is a masculine inanimate noun, its Accusative form is identical to its Nominative form. The actual subject doing the interrupting is шум (noise).
Could I use the verb перебивать instead of прерывать to mean interrupt here?
No, they are not interchangeable. Перебивать is used specifically when you interrupt someone who is speaking (talking over them). Прерывать is used for halting an ongoing process, state, or continuous action, such as a sleep cycle, a meeting, or a television broadcast.
What is the root of the verb прерывать?
It is built on the root -рвать-, which means to tear. The prefix пре- often denotes crossing, stopping, or altering a state. Together, they create the literal imagery of tearing a continuous process apart in order to interrupt it.
