sairastavilla

Sairastavilla is a Finnish grammatical form derived from the verb sairastaa ("to be ill"). It is the adessive plural of the present active participle sairastava, and is used to indicate location, accompaniment or association with people who are currently ill. As an adessive form it can be translated in context as "with the sick," "among the sick" or more loosely "for those who are ill."

Morphology and usage: sairastaa (verb) → sairastava (present participle, "being ill" or "who is ill") → sairastavilla (adessive plural, used when referring to multiple persons or groups in the adessive case). In Finnish syntax it can function attributively with a noun (e.g., "sairastavilla lapsilla" — "with the children who are ill") or be used nominally to refer collectively to ill persons.

Pronunciation and register: stress falls on the first syllable; the word is neutral in register and appears in everyday, medical and administrative contexts where case-marked expressions are required.

Related forms: sairastava (singular participle), sairastavien (genitive plural), sairastavia (partitive plural). For general information on root and usage, see entries on the verb sairastaa and the Finnish case system.
