About
The character "宙" is structurally composed of the "宀" roof radical and the component "由", which historically served both phonetic and semantic functions. Its original meaning pertained to the eaves or ridgepole of a building, an architectural reference derived from its radical. This concrete sense later evolved into an abstract concept, coming to denote a span of time or an era in classical usage. In modern Chinese, its primary application is within the compound "宇宙", where it specifically represents the temporal aspect of the cosmos, paired with "宇" for spatial dimensions.
