About
The character "宇" is structured with the semantic radical "宀", representing a roof or dwelling, combined with the phonetic component "于", which guides its pronunciation. Originally denoting the eaves or physical cover of a house, its meaning gradually extended to include the interior space within a building and then, through a metaphorical shift, broadened to signify the vast canopy of the sky or the infinite cosmos. This semantic expansion is captured in compounds like "宇宙", where it conveys the concept of the universe, marking a transition from specific architectural reference to an abstract representation of spatial expanse.
