The word 仍旧 is formed by combining two independent characters, each contributing its core meaning to create a new, unified concept. The first character, 仍, carries the essential idea of "continuing" or "persisting in a state". It is joined with 旧, which means "old" or "former". Their combination is not merely additive but conceptual; the word literally pictures "continuing in the old way", which directly yields the meaning of "still", "as before", or "remaining unchanged". This formation is a classical example of a Chinese compound where the relationship between the parts is coordinative, building a single idea from the juxtaposition of two foundational notions.
