I'm a few pages into the toki pona lesson plan I'm using (apparently I'm on page 5) -- enough to be able to construct simple sentences like 'I'm asleep' (mi lape) and 'you're funny' (sina musi) and 'they're eating an apple' (ona li moku e kili loje), and then I decided that I wanted to swap to focusing just on vocabulary. I've whizzed through that (I have 70 words/symbols memorised, I expect to be done with the game I'm using to study it within the next couple days -- I don't think this has all words currently in active use but it'll give me the core 120-130 or so). The grammar was a little frustrating to have to keep stopping reading to go remind myself which word means what while doing the exercises, so swapping back when I'm done with the vocab will let it go a bit smoother, I think. I am enjoying myself, though!
Also for anyone wondering, '[sina] o moku e palisa unpa' is 'eat a dick'
