What’s helped for me with 人数 is, instead of the Sue I usually use for 数 mnemonics, I started using Zeus instead. So in this case, Zeus is counting people, his worshipers. Sue has no reason to count people. Zeus does, because he gains power from the amount of people worshiping him.
I dunno if this will help, but it turned from one of my bigger leeches to one of my stronger mnemonics.
My worst leech is apparently 八日, and I believe it. I can never remember if it’s よう or よっ and I always mess it up at the worst time.
I apparently cannot remember the meaning of 転ぶ, which is surprising to me, because although I often get it wrong, I would have thought any of the expectation/anticipation vocab words would be further up on my list.
This is exactly why 四日 is currently sitting at the top of my list. Though, until my morning review session today it was 入所 which is now sitting right above 入場 because I can’t for the life of me keep those sorted.
8 is the bigger number, so 八日 sounds kinda slow and fat, therefore it is ようか (youka) with the longer vowel length. Or, 8 has two small o’s in it, therefore it has a Japanese double-o sound. 4 is smaller, faster, and snappier, therefore 四日 is よっか (yokka). Snap those k’s!
I’m still new, but I just could NOT get 力 through my head! Every time it came up, I would get upset, because I knew that I didn’t know it, despite studying it so hard, both in the SRS method and in the cramming method. I might lose it a little if I meet a person irl whose name is Ricky, lol.
You should remember りょく instead for now. Of WK’s 26 vocab that use 力, 23 use りょく, 2 use りき, and 1 is the vocab word ちから.
If you have some familiarity with the WWE (N64 FTW), you can use The Rock (or the Ryock) and Rikishi (which means sumo wrestler, one of those 2 りき vocab words) as your mnemonics. It may work better than imagining some random dude named Ricky.
公用 is the absolute worst. I am already grinding my teeth when I see it, because I just - know - I will f*ck it up again. I will never ever remember the translation… never.
You can keep me at gunpoint and ask and I will scream, “Public something… thing… action… whatever!!”
Oh yes, and 医学. I - always - hit enter after typing “medical studies” just to scream, “No, wait!! I meant medical science!!”
