tunnelien

Tunnelien is the genitive plural form of the Finnish noun tunneli, meaning "of tunnels" or "tunnels’." It is used in sentences to indicate possession or association with multiple tunnels, for example: tunnelien suuaukot (the entrances of the tunnels) or tunnelien pituus (the length of the tunnels).

Etymology and form: The Finnish noun tunneli is borrowed from the English word tunnel. In Finnish, the standard plural nominative is tunnelit, while the genitive plural is tunnelien. The form tunnelien appears in phrases that express belonging, relation, or description of several tunnels.

Usage: The genitive plural tunnelien occurs across diverse domains where multiple tunnels are discussed. In civil engineering and construction, phrases like tunnelien suunnittelu (design of tunnels) or tunnelien rakentaminen (construction of tunnels) are common. In archaeology or cultural heritage contexts, one might speak of tunnelien tutkimus (study of tunnels) or tunnelien säilyttäminen (preservation of tunnels). In legal or safety texts, expressions such as tunnelien turvallisuusmääräykset (safety regulations for tunnels) can appear.

See also: tunneli, tunneli- as a root term; other Finnish genitive plural forms follow the -ien pattern for many nouns ending in -i. For non-Finnish readers, tunnelien serves primarily as a grammatical form rather than a separate concept.

In summary, tunnelien is a grammatical form used to refer to properties, characteristics, or relations of multiple tunnels within Finnish text, derived from the noun tunneli, itself borrowed from English.
