Uusio

Uusio is a Finnish noun meaning renewal, revival, or rejuvenation. It is formed from the adjective uusi ("new") with the noun suffix -o, which creates abstract nouns that denote a process or state. The word tends to be more formal or literary; in everyday speech speakers often use synonyms such as uudistus ("reform") or uusiutuminen in contexts where renewal is discussed, depending on nuance.

In usage, uusio can refer to the revival of traditions, cultural life, or interest after a period of decline; it can also denote regenerative processes in biology or ecology, or the renewal of energy, materials, or institutions. Because it emphasizes the renewal aspect rather than the act of making something new from scratch, uusio often appears in discussions of long-term cultural, social, or environmental change.

Etymology: from Finnish uusi "new" plus -o, forming an abstract noun that expresses a process toward a renewed state. The construction is similar to other Finnic word formations that capture a state or process resulting from becoming new.
