First of all, is that even what this is, and is there a term for it? For example, in a certain application's settings menu there is an option for vibration sensitivity that looks like this:
強 中 弱
I have three thoughts for what 強 and 弱 might be:
- i-adjectives with the い removed.
- Full words (きょう and じゃく?)
- Not words at all, but Kanji used to convey meaning directly (are these pronounceable then?)
So what are these, and if the answer is option #1 or #3, are there any solid rules for when it is okay to write like this?
