sairaaksi

Sairaaksi is a Finnish grammatical form, specifically the translative case of the adjective sairaas meaning ill or sick. It marks a change of state and is used to express “to become ill” or “to fall ill” in English. In practice, sairaaksi appears in predicates with verbs that denote a change of condition, most commonly with the verb tulla (to become) and, less frequently, with other verbs of change.

Usage and examples:

- Hänestä tuli sairaaksi viime viikolla. (He became ill last week.)

- Potilas tuli sairaaksi tutkimuksen aikana. (The patient became ill during the examination.)

The form indicates a transition into the ill state, distinguishing it from sairaana (being ill at a given time) or sairastua (to fall ill, emphasizing the onset of illness in general).

Relationship to other forms:

- Sairas is the adjective meaning ill. Sairaaksi is its translative form used to express becoming ill.

- Sairastua is another Finnish term meaning to fall ill, often focusing on the onset of illness rather than the resultant state.

- The phrase tullasairaaksi, mutta is typically expressed as tulla sairaaksi rather than a specialized compound.

Notes:

- Sairaaksi functions as a predicative complement in sentences with verbs of becoming and does not stand alone as a noun or adverb.

- Its usage is common in medical, biographical, and everyday contexts to describe transitions to an illness.
