Which reading/meaning of 入り込む is more common？


The word 入り込む has two possible readings いり込む and はいり込む. What exactly is the
more common reading and the difference of the two? Based on my research
online, it seems that はいり込む is more frequently used than いり込む. Is this a
correct assumption?




I would say that this isn't actually a case of one word with two readings, as
you've suggested, but of two different words that are written in the same way.
That distinction may seem trivial, but if you look up the two words in a good
Japanese dictionary, it quickly becomes apparent that it is not.

大辞林 defines 入り{はいり}込む{こむ} as follows:

> 中にはいる。奥深くはいる。 「裏口から－・む」

入り{いり}込む{こむ}, on the other hand, is defined like this:

> ① 強引に中にはいって行く。はいりこむ。 「敵陣深く－・む」
>
> ② 物事が複雑に絡みあっている。入り組む。 「 － ・んだ事情」
>
> ③ 多くの人が寄り集まる。 「人の－・む事多ければ／仮名草子・浮世物語」

As you can see, while the _first_ definition of 入り{いり}込む{こむ} is quite close to
that of 入り{はいり}込む{こむ} (though not precisely identical), 入り{いり}込む{こむ} has two
additional meanings that it does not share with 入り{はいり}込む{こむ} at all.

So when you encounter 入り込む without 振り{ふり}仮名{がな}, your task isn't so much to
determine which of two _readings_ to use, but to figure out which of two
different _words_ (which do have different readings) is intended. In most
cases, context should probably allow you to do this.
