Thread: Ah, This Grammar is Making me Insane!

"подъезжать" includes the meaning of "to approach".

By the way, I think I made an error in my explanation to Astrum:

"where at?" = prepositional case (but after certain prepositions, instrumental)
"where to?" = accusative case (but after certain prepositions, dative or instrumental)
"where from?" = genitive case (nearly always)

Instrumental can definitely be used (with certain prepositions, like под, "underneath") to mean "where at?", but wouldn't be used to mean "where to?" -- at least, I can't think of any common examples that Astrum needs to worry about.
