Meaning and origin of もありか?


> 精霊の身体は人間より遥かに強靭だからな。毒でも呑ませてみようか。ああ、それならば麻薬を打ってみるの **もありか** ……

The speaker was offering some ways to torment a 精霊.

Hi. Does the もありか mean “OK”? But I can only find the word 在り処(ありか), which
means “whereabouts” in dictionaries. Does the ありか come from あるか, which
indicates existence?

Thank you.




This もありか is three words, も + あり + か.

  * **も** is "also".
  * **あり** (also written as アリ, from the masu-stem of 有る) is a noun that roughly means "a good idea", "a possible solution", etc. 
    * [Is アリ in そんなのアリかよ⁉︎ some type of slang?](https://japanese.stackexchange.com/q/43481/5010)
    * [Understanding ありやな](https://japanese.stackexchange.com/q/4642/5010)
  * **か** is a question marker, which in this sentence means "..., I guess".

> ああ、それならば麻薬を打ってみるのもありか……  
>  Oh, in this case, trying narcotic drugs will be good, too, I guess.
