Kosteusalaista

Kosteusalaista is a term in Finnish that does not have a standard, widely accepted definition. It appears mainly in creative, speculative, or limited regional usage as a coined word rather than as a term with official meaning. Etymologically, it combines the Finnish word kosteus (moisture) with a suffix that in some cases forms descriptors of people or groups, but its precise sense is determined entirely by context.

In fiction or world-building, kosteusalaista might denote inhabitants of a humid region or a community distinguished by its tolerance or handling of damp environments. In discussions about buildings, climate, or health, it could be used humorously or hypothetically to refer to people affected by moisture-related conditions; however, it is not an established technical term, and more precise language (for example kosteusvaurio for moisture damage) is typically preferred.

Because the term is not standard, explicit definitions should be supported by sources whenever possible. The word serves as an example of how new labels can be formed in Finnish from base nouns and affixes, illustrating the flexibility of the language.
