Questions & Answers about Вертолёт не смог взлететь из-за сильного ветра.
How does the prefix вз- change the verb in this sentence?
The base verb is лететь (to fly). The prefix вз- adds the meaning of upward motion. Together, взлететь literally means to fly up, which is the standard way to say to take off in Russian.
Why are we using the perfective verbs смог and взлететь here?
The sentence describes a single, specific attempt that failed, rather than a repeated action or a general state of ability. The perfective не смог (could not manage to) pairs with the perfective infinitive взлететь to show this was a one-time event blocked by the wind.
Why does the sentence use из-за instead of потому что for because?
потому что is a conjunction used to connect two full clauses, meaning it needs a new subject and verb. из-за is a preposition meaning because of or due to, which must be followed directly by a noun phrase, like сильного ветра (strong wind). It is also especially common when talking about negative causes or obstacles.
What case is сильного ветра and why?
It is in the genitive case. The preposition из-за always requires the genitive case. The dictionary form is сильный ветер (strong wind), and the masculine endings change to -ого for the adjective and -а for the noun.
