laajuista

Laajuista is the partitive singular form of the Finnish adjective laajuinen, meaning extensive or wide in scope. It is used to describe an indefinite amount or extent of something, such as in phrases like laajuista tutkimusta or laajuista dataa, where the noun is in the partitive case.

Morphology and usage are typical of Finnish adjectives. The base form laajuinen agrees with the noun in number and case, and its partitive singular form becomes laajuista. This form is common when the action or state is not completely bounded or when the noun it modifies is indefinite. The adjective laajuinen is derived from the noun laajuus, which means breadth or extent, itself related to laaja, meaning wide.

Common contexts for laajuista include academic, policy, and general descriptive usage. Examples include laajuista tutkimusta tarvitaan (“extensive research is needed”) and laajuista keskustelua käytiin aiheesta (“an extensive discussion was held on the topic”). The word conveys breadth of scope rather than a precise count, aligning with Finnish grammar’s use of the partitive to express incompleteness or indefiniteness.

Etymology and related forms: laajuinen comes from laajuus (breadth, extent), which is built from laaja (wide) with nominalizing and adjectival suffixes. Related terms include laajuus, laaja (broad), and compound adjectives such as laaja-alainen (broad-based). While laajuista has no independent meaning beyond this grammatical role, it appears frequently in written and spoken Finnish to emphasize scope and magnitude.
