In technical usage, is there any difference between 間投詞 and 感動詞?


デジタル大辞泉 gives the following definition of
[間投詞](http://dictionary.goo.ne.jp/leaf/jn2/49223/m0u/%E9%96%93%E6%8A%95%E8%A9%9E/):

> 《interjection》「感動詞」に同じ。

It also gives the following definition of
[感動詞](http://dictionary.goo.ne.jp/leaf/jn2/49224/m0u/) (emphasis added):

>
> 品詞の一。自立語で活用がなく、主語にも修飾語にもならず、他の文節とは比較的独立して用いられるもの。話し手の感動を表す「ああ」「おお」の類をはじめ、呼びかけを表す「おい」「もしもし」の類や、応答を表す「はい」「いいえ」の類も、文法的性質が同じなので、国文法ではこれに含まれる。
> **間投詞** 。感嘆詞。

Both terms are identically glossed as "interjection" in all the J-E
dictionaries I can find, and the definition for each in デジタル大辞泉 gives the
other as a synonym.

This is the only case I'm aware of where there are multiple ways of referring
to a part of speech (a la 動詞, 名詞, etc.), and so I cannot help but wonder if
there is some technical sense in which these two terms differ.




Shogakukan gives much the same definition. However, I don't think that's
necessarily a big deal -- multiple terms of reference for a single part of
speech is not unknown in Japanese. 形容詞{けいようし}, for instance, have also been
called 形状言{けいじょうげん} and 様言葉{さまことば}. I suspect the difference between 感動詞 and
間投詞 might depend on which grammarian you ask. For what it's worth, the latter
appears to be more of a direct translation of the English term "interjection".
