sanagi

Japanese has distinct terms for the pupa sanagi and the silk cocoon mayu, whereas English often uses 'cocoon' to describe both the silk casing and the pupa inside it.
While 蛹 is the scientific term for an insect's pupal stage, the word 'sanagi' is also used in Japanese poetry and literature as a metaphor for a person undergoing a period of intense internal transformation or waiting for a breakthrough.
In Japanese pop culture, particularly in anime and manga, the term さなぎ is frequently used to describe a 'dormant' or 'incomplete' form of a monster or alien before its final evolution.
