Auf uns zu?
What is the meaning of auf uns zu in "Ein Wagen auf uns zu,"
What is the difference between messen and vermessen?
"vermessen" = the activity of measuring something, e.g. the size of a piece of land, or a room to find out how many rolls of wallpaper you need; anyway a larger object, always concerning lengths, and with more activity involved than just putting a 30cm ruler to it; "messen" = for all sorts of measurement (e.g. temperature, radioactive radiation, density, to what extent people use public transport, ...)
Edit: crossposted with Lukas - he's right, "vermessen" could also mean "to measure wrong", e.g. "Ich habe mich vermessen." It could also mean "presumptious", by the way.
