About
The word 十分 is formed through a conceptual metaphor rooted in measurement. It literally means "ten parts", originally referring to something being divided into ten equal portions. The meaning evolved from this idea of a full, complete division, if something reaches "all ten parts", it is whole, complete, or at its utmost. This notion of fullness was then abstracted to express a high degree or intensity, giving us the modern meaning of "very" or "extremely".
