Questions & Answers about Мы вышли из церкви на улицу.
Why do we use на instead of в for "into the street"?
In Russian, streets are treated as open surfaces rather than enclosed spaces, so you go "onto" them. You use на rather than в (inside). Because this sentence shows motion toward a destination, улица takes the Accusative case, becoming улицу.
What happens to the spelling of церковь (church) here?
The word церковь has a "fleeting vowel." When the word changes its form for different grammatical cases, the о drops out. The preposition из (out of) requires the Genitive case. Because церковь is a feminine noun ending in a soft sign, it takes an -и ending, resulting in церкви.
How does the verb вышли pair with the preposition из?
The verb вышли (went out) is built with the prefix вы-, which means "out." In Russian, verbs of motion with the вы- prefix almost always pair with the preposition из (out of + Genitive case) to cleanly express exiting an enclosed space.
Why is вышли used here instead of the imperfective form выходили?
