folyókból

Folyókból is a Hungarian grammatical form meaning “from rivers.” It is the ablative plural form of the noun folyó (river). In Hungarian, the postpositional suffix -ból/-ből expresses origin, and when attached to the plural stem folyók the result is folyókból. The form indicates that something comes from multiple rivers rather than from a single one.

The usage of folyókból is common in geography, hydrology, environmental science, and everyday language when describing sources or origins. It can refer to water, sediments, pollutants, data, or other materials that originate in several rivers. The same idea can be expressed with related phrases such as folyókból származó, which means “derived from rivers” or “originating from rivers,” used to describe samples, data, or indicators.

Examples include:

- Az ivóvizet a folyókból nyerik ki. (Drinking water is drawn from rivers.)

- A folyókból származó adatok alapján készítették a jelentést. (The report was prepared based on data originating from rivers.)

- A vizsgálat kimutatta a folyókból származó szennyeződések hatását. (The study detected the impact of pollutants from the rivers.)

Notes: folyókból is contrasted with forms like folyódból (from the river) and folyókból való, as appropriate to number and grammatical context. The term is primarily a descriptive, non-figurative usage in a neutral, informative style.
