'And "vomit" has entirely different meanings in German and English.'
There is no word "vomit" in German. "Womit" means "with which" and is pronounced "Voh mit" with a long "o" as in "woe".
However, English-speaking students of German are often amused that the word for "trip" or "journey" is "Fahrt" (with a long "ah" sound, however) and especially by the expression "gute Fahrt" for "bon voyage".
