I have t. Saturn in my third house in Sadge.  I have become clear and purposeful in all my daily communications.  Any short trip I take has a purpose or I don't do it.  I kind of like this.

t. Saturn is opposed to my Jupiter in the 9th house which is usually very open minded.  Its a challenge to that philosophy for me and I've learned a lot from it.  I see the opposition of n. Jupiter in Gemini and t. Saturn in Sadge as a challenge to my embedded ideas.

Buendia, beautiful question there.

You might feel it more keenly, but, a great many adult learners of second languages feel awkward, and shy (one of the facets of Saturn kind of fear) about "looking incompetent" while gaining mastery of a new language.  I know it from experience, and knowing people who also struggled with becoming fluent in a second language.

An ESL teacher (and author on her topic) told a roomful of parents: reaching fluency requires a minimum of x hours (sorry, I forget the number) of striving to use the language you're learning.  A matter of reaching saturation, in your brain.  Things like listening to films, tv, songs, humorists, etc. all help to process - as does reading out loud, when alone and reading in that language.  Two languages is still a rather low number, as anyone outside of North America thinks (says me, fluent in only two). 🙂

ETA I forgot to share my own experiences of natal Saturn in 3rd house, in part because what you wrote reflects already whatever I would have found to say.  I am endlessly happy to improve my facility with words (and with listening to others with an open mind & heart, another 3rd/Gemini function).  So, it that vein, the word "ironically" doesn't quite mean what I mean, when I use it!  "Oddly" would fit better some of those times.  Some other times, I mean, serendipitously (or that Buddhist/Jungian term, synchronously - or synchonistically, more likely).
