I can't come up with an example right now. But hypothetically let's say there was a word that was ka. And they combined it with ku to make a new word. then it'd become kagu instead of kaku. It usually gets softened like that. Why is that?

  • A good example for this would be a word like 口{くち}becoming softened when joined with 入{い}り to form 入{い}り口{ぐち}
