ARCarty, a warning about the first word, аудирование.
It is "audi..."+ -ier-, a German suffix we use to form verbs form loans (which is in turn Latin/romance infinitive ending).
Function - > функция -> функционировать.
I'm an educated Russian speaker who've studied a numebr of languages and linguistics. I've NEVER used this word, not a single time in my life.
But it is abundant in literature about second language education. An _educated_ Russian who hasn't dealt with the field will understand it. I have no idea about less educated Russians.
On the other hand, when I hear this word form a person I know that this person has to do with language education.
