Laajenevien

Laajenevien is a Finnish grammatical form derived from the present active participle laajeneva, which comes from the verb laajentua meaning to widen or expand. The form laajenevien specifically functions as the plural genitive of the participle, and it is used to describe multiple subjects that are in the process of expanding. In Finnish, present active participles behave like adjectives and decline to agree with the noun they modify, including in genitive constructions such as laajenevien alueiden.

Grammatical details and usage notes:

- Construction: laajenevien is the plural genitive form, commonly appearing in phrases where the participle modifies a noun in the genitive or forms part of a larger noun phrase. The coordinating noun often appears in genitive, for example laajenevien alueiden suunnittelu (the planning of expanding areas).

- Agreement: Like other participles, laajeneva-based forms agree in number and case with the nouns they modify. Laajenevien functions as a plural genitive modifier.

- Register and context: The form is typical in formal, academic, or technical Finnish, such as urban planning, geography, environmental policy, and research texts. It is less frequent in casual, everyday speech.

Examples:

- Laajenevien alueiden kehittäminen vaatii investointeja. (The development of expanding areas requires investments.)

- Tutkimus keskittyy laajenevien alueiden riskien ja mahdollisuuksien arviointiin. (The study focuses on assessing the risks and opportunities of expanding areas.)

Etymology:

Laajeneva is formed from laajentua with the present active participle suffix -va/-vä. The plural genitive suffix -ien marks the participle when it modifies a plural noun in genitive form, resulting in laajenevien.
