What does やや書 indicate?


What does the "marker" (?) **やや書** used in Japanese-English dictionaries
indicate?

In addition how would you pronounce the phrase when citing someone a
definition from a dictionary? やや書{しょ}? やや書{かき}?

I cannot pinpoint any pattern in below examples and I can't find a definition
of the phrase itself. Trying to devise its literal meaning "usually in
writing" (?) does not really match the examples (why "insecure" would be
marked as a written form?)

> ときの声を上げる  
>  : shout [ **｟やや書｠** raise] a war cry.
>
> [2] 疑わしい doubtful  
>  : （不確実な） uncertain; （不安定な） unsteady, **｟やや書｠** insecure; （信用できない）
> unreliable.
>
> やや  
>  : 〖少し〗a little, ｟話｠ a (little) bit; 【少しばかり】slightly; 【いくぶん】rather
> (!控えめにいってかえって意味を強める) , **｟やや書｠** somewhat (!rather より客観的な語) ; 【ある程度まで】to
> some extent.
>
> さしおく 差し置く  
>  : (意図的に無視する) ignore, **(やや書)** disregard; (そのままにしておく) leave.




For this sort of question, you should check the 凡例 of the dictionary.

The [Wisdom E-J](http://www.sanseido.net/main/dictionary/hanrei/wisdomEJ.aspx)
defines 話 and 書 like this:

[code]

    　〔話〕　　　(話し言葉(spoken))
    　〔書〕　　　(書き言葉(written))
    
[/code]

The [Wisdom J-E](http://www.sanseido.net/main/dictionary/hanrei/wisdomJE.aspx)
defines them like this:

[code]

    　〔話〕　　　口語
    　〔書〕　　　改まった語，文語
    
[/code]

But I think the abbreviations must still come from 話し言葉 and 書き言葉, in any case.

So in this case, I think `書` is a dictionary-specific abbreviation indicating
`書き言葉` 'written language'. They're suggesting that the English translation
marked with `やや書` is a bit more characteristic of written language than
spoken.
