Kertaantuvia

Kertaantuvia is a Finnish term that functions as the plural form of the adjective kertaantuva, meaning “recurrent” or “reoccurring.” It is used to describe phenomena, events, or observations that occur repeatedly or with some regularity. The base verb is kertaantua, “to recur.” In Finnish, the suffix -va/-vä forms adjectives from verbs, and -ia marks the plural in the partitive case when the noun being described is in partitive. Therefore kertaantuvia ilmiöitä means “recurrent phenomena.”

Usage and nuance: The term is common in scientific, academic, and journalistic writing when highlighting patterns that repeat over time. It emphasizes recurrence rather than mere frequency, and it can carry a sense of persistence across intervals rather than a one-time repetition. It is close in meaning to toistuva (repeating) but carries a nuance of periodic reappearance or persistence.

Examples: Kertaantuvia virheitä esiintyy usein ohjelmistojen testauksissa. Kertaantuvia sääilmiöitä ovat toistuvat sateet ja ukkoset. Tutkimus tarkastelee kertaantuvia ilmiöitä ilmastomallinnuksessa.
