Is the 出し in the following sentence a relative clause?


Is the 出し -which I believe to be 出す- in the following text a relative clause,
as the 行動 is a noun?

> 「ここにじっとしていてもしょうがない………か」
>
> 自分を奮い立たせるために、わざと自分の考えを声に **出し行動** を始めた。




No. 出し is a [**連用形**](https://japanese.stackexchange.com/a/65953/5010), which
means it **never** modifies a noun as a relative clause. 連用形 literally roughly
means "continue- **verb** -form". That 出し modifies nothing. Just because a
verb comes before a noun doesn't mean it's a relative clause.

Compare the following two sentences.

>   1. グラウンドを **走り** 先生を呼んだ。  
>  I ran across the ground and called my teacher.
>
>   2. グラウンドを **走る** 先生を呼んだ。  
>  I called my teacher who was running across the ground.
>

走り is a 連用形, so it does not form a relative clause. This 走り is interchangeable
with 走って. On the other hand, 走る is a 連体形 (≒dictionary form), so it forms a
relative clause that modifies 先生. Please review the basic grammar of relative
clauses.

Perhaps you need some exercise. Only two of the following six sentences
contain a relative clause. Can you tell which?

  1. 彼はイチゴを食べ鳥を捕まえた。
  2. 彼はイチゴを食べて鳥を捕まえた。
  3. 彼はイチゴを食べる鳥を捕まえた。
  4. 彼女は山に登るシカを見た。
  5. 彼女は山に登りシカを見た。
  6. 彼女は山に登ってシカを見た。
