Questions & Answers about Этот этап начинается только по завершении проверки.
Why does завершении end with two и's instead of the standard Prepositional -е ending?
The dictionary form is завершение (completion), which ends in -ие. Neuter nouns ending in -ие take -ии in the Prepositional case instead of -е. Since using по to mean 'upon' or 'immediately after' requires the Prepositional case, the correct form is по завершении.
Could I just say после завершения instead of по завершении?
Yes, после завершения (using the preposition после + Genitive case) means almost exactly the same thing. However, the structure по + Prepositional is more formal and emphasizes that the next stage begins immediately upon completion. You will frequently see it in official, technical, or business contexts like this one.
Why is the reflexive verb начинается used here rather than just начинает?
In Russian, you must use the reflexive form начинаться when an event is starting but not doing the starting to a direct object (intransitive). Since the stage (этап) is just beginning itself, rather than starting something else, it requires the reflexive ending -ся.
Why is проверки in the Genitive case?
It translates to 'of the check' or 'of the inspection'. When you have a noun derived from a verb, like завершение (completion), the target of that action takes the Genitive case. So, завершение проверки literally means 'the completion of the check'.
