virtaamasta

Virtaamasta is a Finnish noun form derived from virtaama, meaning flow or discharge, and is used to express origin or source related to that flow. In technical Finnish, virtaamasta can appear in phrases indicating something derived from or occurring because of the flow of water, such as in hydrological or environmental contexts. As a standalone lexical item, virtaamasta does not function as an independent word with a widely used meaning; rather, it is a grammatical form used within longer expressions.

Etymology and grammar: virtaama is the base noun meaning flow or discharge. The suffix -sta/-stä marks the ablative case, yielding virtaamasta to mean “from the flow.” This form is typical of Finnish noun inflection and appears mainly in formal or technical prose rather than in everyday speech. The construction is consistent with how other -ma nouns behave when treated grammatically in phrases that denote origin, source, or cause.

Usage and context: In hydrology, virtaama refers to the volume or rate of water flow in a channel. Virtaamasta is most likely to occur in sentences describing data, processes, or phenomena that originate from discharge, such as “virtaamasta saadut mittaustulokset” (data obtained from the discharge) or similar specialized phrases. Due to its technical nature, virtaamasta is uncommon outside scientific or linguistic discussions about Finnish grammar and term formation.
