I'm trying to translate into English the three-word motto of a student newspaper from around 1880.
That motto is "Prosta Ac Vince."
Knowing some Latin, I think the motto means "Step Forth and Conquer" -- but I am merely guessing.
Can anyone confirm the meaning of the phrase? (I myself can find the phrase "ac vinci" in at least one very old source, but w/o a translation; and I cannot find the entire phrase in any published work, except in the student newspaper in question.)
