About
The character 宇 is a phono-semantic compound, combining the semantic radical 宀 (mián, "roof") with the phonetic component 于 (yú). Its original meaning referred to the eaves or overhang of a roof, directly connected to architecture and shelter. This concept of a protective covering then extended to mean a house or dwelling, and further expanded to encompass all physical space. When paired with a character representing time, it forms the term for universe, conceptualizing all of existence as a vast, enclosing canopy.
