sairaaisiin

Sairaaisiin is the illative plural form of the Finnish word sairas, meaning sick or ill, and is used to refer to a group described as sick. In Finnish grammar, illative forms indicate movement toward or direction to something or someone; the plural form sairaaisiin is used when the reference is to multiple sick people or patients.

The form sairaisiin is created by applying the illative plural suffix to the stem of sairas. It is most commonly encountered in formal or institutional language, such as medical or charitable contexts, where one writes about actions directed toward or intended for the sick. In everyday speech, other constructions might be preferred depending on the specific verb or phrase being used.

Etymologically, sairaas- derives from the Finnish root for illness or sickness, with the standard illative plural suffix -iin added to yield sairaaisiin. This pattern is part of Finnish case and number morphology, where nouns and adjectives can take different endings to express nuance of direction, purpose, or recipient.

Notes: Sairaaisiin is a grammatical form rather than a concept with independent meaning. Its usage hinges on context involving groups identified as ill or patients, and it should be distinguished from singular forms such as sairaaseen (to the sick person) and from other plural forms used for different grammatical cases. For learners, recognizing sairaaisiin as the illative plural form of sairas helps in parsing sentences that describe actions directed toward a group of sick individuals.
