Tiiviyteen

Tiiviyteen is a Finnish term that appears in discussions of increasing density or compactness. It is not a fixed technical term with a single universal definition; its precise meaning depends on the field and context.

In urban planning and housing policy, tiiviyteen commonly refers to densification strategies: increasing the number of housing units per geographic area, promoting mixed-use and higher-density development within existing city centers, and supporting efficient public transport. Proponents describe tiiviyteen as a way to curb urban sprawl and make better use of land and infrastructure; opponents worry about crowding, changes in neighborhood character, and affordability.

In materials science and manufacturing contexts, the term can denote the process or result of densification, where a granular or porous material is made more compact through techniques such as sintering, hot pressing, or compaction.

Etymology: Tiiviyteen is formed from tiivi (dense, compact) plus the illative suffix -teen, which indicates direction or transition into density. It functions as a neologism more common in Finnish-language discourse than in English-language literature.
