Questions & Answers about Мы проезжаем мимо красивого озера.
How does the preposition мимо affect the words that follow it?
The preposition мимо means "past" or "by" and always requires the Genitive case. Because of this, both the adjective красивое and the neuter noun озеро change to their Genitive forms, becoming красивого озера.
Could we just say Мы едем мимо instead of using проезжаем?
You can say Мы едем мимо, but проезжаем is much more natural and precise here. The prefix про- added to a verb of motion specifically means "to pass by" or "to go past". It pairs perfectly with мимо to emphasize the action of passing a specific location while in a vehicle.
I keep forgetting: how exactly is the ending of красивого pronounced?
It is pronounced with a "v" sound, not a "g"! The Genitive masculine and neuter adjective endings -ого and -его are always pronounced as if they were written with a "v" (like -ово or -ево). So, красивого sounds roughly like "kra-SEE-va-va".
