pankeista
Pankeista is a Finnish word built as the elative plural form of the noun pankki, meaning "from the banks." In Finnish, the elative case expresses origin or source, and when applied to the plural banks it yields pankeista, i.e., "from the banks." It is a neutral, grammatical form used in standard language.
Pankeista indicates the origin or source of something that involves multiple banks. It is used with verbs
- Rahoitus tuli pankeista. (The financing came from the banks.)
- Tiedot ovat peräisin pankeista. (The information originates from the banks.)
- Neuvot perustuivat pankeista saatuun dataan. (The advice was based on data obtained from banks.)
For a single bank, pankista is used — not pankeista.
Pankki (bank) → plural pankit; elative plural suffix -ista yields pankeista.
