kapeaaukkoista
kapeaaukkoista is a Finnish term that literally translates to "narrow opening" or "tight aperture." The word is formed from kapea, meaning narrow, and aukko, meaning opening, and the suffix –ista indicates a plural form or a noun derived from a descriptive adjective. In contemporary Finnish, kapeaaukkoista is used in various technical and everyday contexts whenever a small, restricted passage is being described. Examples include architectural descriptions of tight corridors, mechanical engineering references to narrow valves or vents, and biological discussions of slender apertures in shells or plant structures. In informal speech, the term can also be applied metaphorically, for instance to describe a narrowly focused perspective or limited viewpoint, although that usage is less common in written literature.
The term appears in dictionaries and specialized glossaries, and it is frequently encountered in Finnish textbooks
