Sorry, I misinterpreted your context.
You wanted to introduce the notion of "bound morpheme". It can provide a clue to consider this matter.
Technically speaking, bound morpheme also refers to suffixes like 的 of 圧倒的 so it cannot be a direct answer to this question but it is intriguing notion.

As this exchange shows, grammar in Japanese could be very technical and academic issues.
It's not something ordinary people care about.
