This post is going to be brief. I have only two points to make regarding dedicated language study.
1. Write it down.
2. Read aloud.
You can’t learn any language well just by reading it over and over again. You have to write it down, get a feel for how the words dance together, how the accents flit across the tops of the words. You need to make your own hand and brain connect as you re-compose the letter, the story, the speech. Make it your own. Write it down.
What is the point of language if you aren’t saying anything? Speaking in your head is like praying in your head; Samuel thought Hannah was drunk. That means what she was doing probably wasn’t normal. Find a quiet place or go on the street corner if you dare and read your text aloud (that’s not normal either but Samuel’s dead, bro). Read aloud your Greek, Latin, German, Finnish, Creole texts (English for some of you) and make your voice and your brain connect as you rehearse the lines of the ancient play you are now a principal actor in. Make it your own. Read aloud.
Below is a visual from my own daily work of memorization. Whoever comments first with the correct identification of where this is from, you get mad props. And then you better go and do likewise.
