Vaihtuvilta

Vaihtuvilta is the plural ablative form of the Finnish adjective vaihtuva, meaning changing, variable, or alternating. It is used when the noun it modifies is plural and in the ablative case, indicating origin or source from changing things. The form is common in contexts such as data, measurements, or sources that vary.

Etymology and morphology: The base adjective vaihtuva is formed from the verb vaihtua (to change) with the adjectival suffix -va. In Finnish, adjectives inflect like nouns for case and number; the ablative plural suffix -ilta/-iltä attaches to the modified noun, yielding vaihtuvilta when the adjective precedes a plural noun in the ablative.

Usage: Vaihtuvilta tends to appear in academic or technical Finnish to describe data or sources that are not constant. The phrase often occurs with a following noun in ablative plural, e.g., vaihtuvilta lähteiltä or vaihtuvilta mittauksilta, meaning “from fluctuating sources” or “from varying measurements.” Note that vaihtuvilta by itself does not convey a complete idea; it is part of a larger noun phrase.

Example: Tiedot kerättiin useilta vaihtuvilta lähteiltä.
