Question: how to use etwas in german?
Answer: Sometimes you can use both "einige" and "etwas", i.e. you can say "Mit einigem Glück" (which means you need quite some luck) and "Mit etwas Glück" (-> a little luck...) but in those cases, "etwas" is less than "einige". Ich brauche etwas frisches Fleisch.
