Do all nouns from verbs nominalized by the suffix "-ung" have a female gender?

Question

By suffixing verbs with *"-ung"* we can build nouns, e.g.: > prüfen - Prüfung meinen - Meinung richten - Richtung All those nouns seem to have a female gender. Is that always true or do we have exceptions from that rule?

Answer 1

You are correct! All nouns ending in -ung will be feminine. (I think this might be one of the only hard-and-fast rules when it comes to German noun gender.)
