Interesting moment this week where I struggled with a grammar exercise and then realized upon review it wasn't the grammar, it was the vocab I was getting wrong.
It's starting to dawn on me, between this and feeling like I'm getting somewhere close to particle mastery, that I don't have much all that much farther to go on grammar learning. Stopped seeing new particle forms and verb conjugations a long time ago, there's far more grammar concepts behind me than there are ahead (assuming I don't do something wild like dive into Chinese literature study or old books). Maybe it's typical for reaching the end of the intermediate journey? Everything becomes vocab, vocab, vocab.
I might already be at the point where I need to start trusting my grammar forms over my vocab knowledge when a sentence doesn't make sense. I've been an Anki warrior for so long that it's a weird switch to flip in my head.
