esiintyneitä

Esiintyneitä is Finnish, formed as the plural partitive of the past participle esiintynyt, from the verb esiintyä meaning to appear, to occur, or to perform. The form esiintyneitä is used to describe things that have appeared or been observed, and it functions as an adjective-like modifier that agrees with nouns in partitive case.

In usage, esiintyneitä is most common in medical, scientific, and formal contexts, where it refers to symptoms, cases, or phenomena that have appeared or emerged. Examples include esiintyneitä oireita (symptoms that have appeared), esiintyneitä tapauksia (cases that have appeared), or esiintyneitä ilmiöitä (phenomena that have appeared).

Grammatically, esiintyneitä corresponds to the plural partitive form. Other related forms include esiintynyt (singular nominative or past participle) and esiintyneet (plural nominative). The choice of form depends on the case and number of the noun it describes.

- Potilailla esiintyneitä oireita olivat kuume, yskä ja väsymys. Translation: Among patients, symptoms that had appeared were fever, coughing, and fatigue.

- Tutkimuksessa raportoitiin esiintyneitä tapauksia. Translation: The study reported cases that had appeared.

- Esiintyneitä reaktioita havaittiin hoidon alussa. Translation: Reactions that had appeared were observed at the start of the treatment.
