Meaning and origin of もありか?

Question

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.

Answer 1

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?
  • Understanding ありやな
• 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.
