Help with numbers, counting, things, days, months

Hi, I’m struggling on these:

Kanji Radical Combination On’yomi Kun’yomi Thing (つ) Day (日) Month (月)
1 Ground いち, いつ ひと ひとつ いちにち いちがつ
2 Two ふた ふたつ ふつか にがつ
3 Ground + Two さん みっつ みっか さんがつ
4 Mouth + Legs よん, よ よっつ よっか しがつ
5 Five いつ いつつ いつか ごがつ
6 Lid + Fins ろく むっつ むいか ろくがつ
7 Seven しち なな, なの ななつ なのか しちがつ
8 Fins はち や, よう やっつ ようか はちがつ
9 Nine く, きゅう ここの ここのつ ここのか くがつ
10 Cross じゅう とお とお とおか じゅうがつ

Month is ok as that follows the ‘On’yomi + がつ’ and is consistent, but I struggle with the Thing / Day inconsistencies.

I like the idea of this chart Remember all the different numbers - #7 by cantoryakov and wondering if anyone has any other recommendations, patterns, mnemonics to help please?

どうもありがとうございます🙇🏻‍♂️

Just looking at the very first line, ついたち isn’t used for counting days. One day is just ichinichi. Tsuitachi is for the first day of the month, which is a bit different. If you’re aware of that, then we all good, but i wasn’t sure if you were aware of the difference in those two words so figured I’d say something.

Also ten things is とお

That chart basically covers all of the exceptions - aside from that it’s pretty consistently on’yomi+counter. The main exceptions remaining are:

  • 四 and 七 use their kun’ and on’yomi fairly interchangeably, because they like to be weird like that, but there are some cases where one reading or the other is always used. For example, 四人 is always よにん, because しにん sounds like 死人 which means “corpse”. (And on that note, 四 occasionally drops the ん from its kun’yomi, because it’s easier to say.)
  • Sometimes counters get rendaku’d, and sometimes they get geminated. For example, 匹 (counter for small animals) is read as ひき, but for example when it’s 六匹 the reading is ろっぴき. These follow the standard rendaku and gemination rules, so you’ll get the hang of it over time.

Wikipedia has a pretty good article on the subject:

To be clear, it’s とお with no つ.

The kun’yomi numbers do continue past ten, but you’ll basically never ever see those in modern Japanese. The 個 (こ) counter is used instead, with on’yomi numbers.

Edited to avoid confusion.

I mean technically it can be, but almost no one ever uses that. Most people use 個. You’re about just as likely to see 个 as you are to see 箇 in my experience.

I blame the IME for that one. :stuck_out_tongue:

Thanks, I’ve updated these :slight_smile:

Thanks, I’ll have a read. “standard rendaku and gemination rules” - I’m not familiar with these so I’ll do some research, thanks again!

What is IME please?

Input method editor. Basically the thing that allows you to type in japanese and parse hiragana into kanji. He’s saying he blames that function for giving him the wrong kanji when he typed ko
