vakioihin

Vakioihin is the illative plural form of the Finnish noun vakio, meaning a constant, fixed value, or standard. In mathematics and physics, a vakio refers to a quantity that does not change under the conditions described by a formula or model. The illative plural vakioihin is used when discussing multiple constants as a group or when indicating movement or reference toward the constants in a sentence.

Morphology and usage: vakioihin is formed by adding the illative plural suffix -iin to the stem vakio-, resulting in vakioihin. The form is common in technical and scientific writing, where writers refer to a set of constants such as pi, e, Avogadro’s constant, or Planck’s constant. A typical construction is vakioihin kuuluvat, meaning “belong to the constants” or “are constants.”

Examples: Laskentakaavassa vakioihin kuuluvat pi ja e. In this sentence, pi and e are identified as constants within the formula. Another example might refer to physical constants grouped together in a discussion of units or invariants.

Other senses: vakio can also denote a fixed price or standard procedure, as in compound words like vakiohinta (“fixed price”) or vakiorutiini (“standard routine”). The noun’s broader sense as a standard or invariant value is common in Finnish technical language.

Notes: vakioihin is primarily a grammatical form used in formal, academic, or technical contexts. In everyday Finnish, speakers more often refer to “vakiot” (constants) or specify individual constants rather than employing illative plural forms. See also vakio and illatiivi in Finnish grammar.
