Arkeista

Arkeista is a Finnish grammatical form and not a separate lexical entry. It is the elative plural form of the noun arki, which can mean either a weekday/workday or ordinary daily life, depending on context.

The noun arki has two common senses. In the sense of time, arki refers to the weekdays or the regular workdays of a week. In the sense of lived experience, arki means everyday life or routine. The form arkeista is used when referring to sources or origins that come from multiple weekdays or from everyday-life contexts, depending on which sense of arki is intended.

Morphology and usage: arkeista is formed by taking the base arki and applying the elative plural suffix -eista. The singular elative is arkista, and the genitive plural of arki is arkien. As with other Finnish inflectional forms, the exact nuance of arkeista is determined by the surrounding context and the intended meaning of arki in that passage.

In practice, arkeista appears in statements about data, observations, or descriptions tied to a period or to everyday life that spans several days. For example, tilastot ovat koottu arkeista would translate to “the statistics have been drawn from the weekdays” (or from weekday data). In other contexts, arkeista may indicate sources rooted in daily-life situations, though the everyday-life sense is more commonly expressed with other forms such as arjen.
