maakunnista

Maakunnista is a Finnish word formed as the elative plural of maakunta, meaning roughly "from the regions" or "out of the regions". Grammatically it combines the plural stem with the elative suffix -ista/-istä, following Finnish consonant gradation and vowel harmony rules (maakunta → maakunnista). The form is used to indicate origin, source, separation or topics that concern multiple regions.

In administrative and geographic contexts, maakunta (plural maakunnat) refers to Finland's regional units, and maakunnista appears in phrases discussing information, movement, comparisons or issues derived from those regions (for example: "tiedot maakunnista" — "information from/about the regions"; "tulossa maakunnista" — "coming from the regions"). It also occurs in wider discourse when referring to characteristics, resources or problems that originate in or relate to several regions.

As a case form, maakunnista is one of many Finnish locative cases used to express spatial, causal or partitive relations; its use depends on verb and preposition patterns and on the intended nuance (physical origin, source of data, or topic of discussion). The corresponding basic forms include maakunta (nominative), maakunnat (nominative plural) and maakunnasta (singular elative), each serving different syntactic roles in Finnish sentences.
