@Szymon I upvoted it after I saw the screen shots. They convinced me :-)

@Szymon I agree it's good to have multiple answers a lot of the time.

The reason I didn't upvote your answer right away is because it's somewhat outside my personal experience

All I can do personally is describe the stuff I'm familiar with

So the screen shot helped me make my decision :-)

Hee.

Well, I think you wrote the best one.

I wrote a bunch of answers today.

Five! A bunch is five.

Yeah, it's a 熟字訓読み

@小太郎 I think in principle it could be either one

If it gives furigana then go with what the furigana say

熟字訓 is when a 訓 reading is assigned to the combination of multiple characters, rather than to an individual character

Like 吹雪 = ふぶき

I'm having trouble justifying that in the case of お腹

But I think it is. Hmm.

But often it's a mapping from one compound (in this case 御中 = おなか) onto different kanji (御腹 I guess, but I only ever see it written お腹)

Ah, I can find some instances of 御腹 online, so I'll stick with that theory :-)

Anyway, it never appears as なか outside of that word

It's not used to write the word なか, only as part of お腹 to write the word おなか

I guess since おなか is a lexicalized combination, in this case なか doesn't represent a single word

Am I wrong? Should it just be considered a regular 訓 reading that isn't on the 常用漢字表?

Yeah, well, there are lots of quirks to the official lists of stuff.

Officially, you're s'posed to write that word in kana.

But until 2010, 誰 wasn't on the official list :-)

While 虞 and 璽 were...

So it can be kind of silly talking about the official lists of stuff sometimes.

Haha!

Now you can read the Japanese constitution!

乃至！

I like to read 〜 as 乃至

There's a big list, and おなか ain't on it.

Maybe it's just a regular kun'yomi which is, for some reason, not included in any dictionary I've checked.

See, these dictionaries aren't limited to jōyō readings, so I'd expect them to list it as a non-jōyō kun'yomi if it were one. I think that's why I always assumed it was a jukuji kun'yomi

Hey, the New Nelson lists it :-)

That's my first time using the New Nelson in at least a year.

@ssb It's kind of long.

I started reading it once but my attention wavered

I'm not sure I could read through the U.S. Constitution again unless I divided it up into a bunch of pieces. I'd probably zone out part way in...

Syntax, though, I can't get enough of ;-)

Maybe I should ask a question about what sort of reading おなか is

I thought I knew, but after talking about it here I'm not so sure :-)

I might turn our discussion about reading 息を吐く into a question, too
