kyselyaikojen

Kyselyaikojen is the genitive plural form of the Finnish noun kyselyaika, meaning “survey period” or “time window for a questionnaire” in research and data collection contexts. The word is used to refer to multiple periods during which surveys are conducted or planned. It appears in academic writing, market research reports, public opinion polls, and administrative planning where several survey rounds are discussed.

Kyselyaika is a compound of kysely (“survey, questionnaire”) and aika (“time”). The genitive plural suffix -ojen marks possession or association with multiple periods: kyselyaikojen pituus = “the length of the survey periods,” kyselyaikojen suunnittelu = “planning of the survey periods.”

Usage and nuance: The form is grammatical and functions as a genitive plural, not as an independent lexical item. It commonly appears in noun phrases to specify attributes of multiple survey periods. The phrase is formal and typical of written Finnish; in everyday speech speakers may opt for simpler constructions such as “kyselyaikojen kesto” or rephrased forms.
