I brushed up on the use of Japanese commas (読点)
[here](https://japanese.stackexchange.com/questions/3786/usage-of-commas-in-
japanese-sentences), but I don't think it explained this usage I found on
[知恵袋](http://detail.chiebukuro.yahoo.co.jp/qa/question_detail/q1435818124).

The sentence is this:

```

    忙しい、の対義語に当たる形容詞は何でしょうか。
    
```

Why exactly is the OP using the comma like this? The rule of thumb for me in
English is that if you pause when speaking, you should use a comma in writing.
I've just carried that over to Japanese somewhat, but this sentence would
sound very unnatural to my (non-native) ears if one where to pause after 忙しい.
Is that just not the case? Is this a standard use of the 読点 or internet slang,
or...?

question
grammar punctuation
Use of a comma to separate a single word
Strictly speaking, I think it should be

> 「忙しい」の対義語に当たる形容詞は何でしょうか。

but the person wrote it as

> 忙しい、の対義語に当たる形容詞は何でしょうか。

probably because s/he thought it wouldn't cause any confusion (and maybe
because s/he was just being lazy; I might do that too when I want to save the
trouble of typing the brackets :p). If it was like

> 味でなく、考え方などについていうときの「甘い」の対義語に当たる形容詞は何でしょうか。

then...

> 味でなく、考え方などについていうときの(、)甘い、の対義語に当たる形容詞は何でしょうか。

might look a bit confusing and it might be a bit harder to realize how it's
parsed at first glance.
