さくらさくらの「ぞ」はどういう意味？


桜桜の歌詞で「匂いぞ出{い}ずる」と言った（どうやっていうの？）文があります。その文のぞはどういう意味ですか？助詞じゃないですか？

I don't really know how well I structured that. In any case, what is the
functionality of ぞ in さくらさくら? I can only find web definitions for emphasis, at
the end of sentences.




This 「ぞ」 is a 係助詞{かかりじょし} (binding particle) from classical Japanese.

**History** : It was originally そ in the Nara period, then ぞ in the Heian
period, gone in the Muromachi period except for people intentionally trying to
sound poetic, such as the author of this poem.

**Semantics** : It stresses/emphasizes what it marks

**Syntax** : It occurs in the usual spots of a 係助詞 (the syntactic class
containing は, も, こそ, でも, etc.), but in addition, it is followed by the 連体形 of
a verb -- this phenomena occurs with a few other 係助詞 in Classical Japanese and
is called 係り結び.

**Examples** :

> 右近 **ぞ** 見知りたる。呼べ！  
>  ukon zo misiritaru. yobe.  
>  "Ukon knows for sure. Call her!"
>
> みな鎧の袖を **ぞ** ぬらしける。  
>  mina yorohi no sode wo zo nurasikeru.  
>  " _Everyone_ wet the sleeves of their armor."

In your case:

> 霞か雲か 匂い **ぞ** 出{い}ずる  
>  kasumi ka kumo ka nioi zo izuru  
>  "Is it mist? Is it a cloud? The color radiates!"

(This 出ずる is in fact a newer spelling of the 連体形 of the
下二段活用動詞「[出づ](http://kobun.weblio.jp/content/%E5%87%BA%E3%81%A5)」, 「出づる」,
meaning that this sentence fits the bill.)
