tauteihin

Tauteihin is the illative plural form of the Finnish noun tauti, meaning disease or illness. In Finnish grammar, the illative case marks movement toward or into something; tauteihin therefore means into diseases or to diseases, used with verbs that express becoming ill or contracting illnesses.

Use and meanings

The form tauteihin is typically used with verbs such as sairastua (to fall ill, to contract an illness). For example, Hän sairastui tauteihin means “He fell ill with diseases” or “He contracted illnesses.” The construction signals that the illness is plural in scope, referring to more than one disease in the context of becoming sick.

Morphology and related forms

Tauteihin is the illative plural of tauti. Related forms include taudit (nominative plural, diseases), taudin (genitive singular), taudeissa (inessive plural, in diseases), and taudeista (elative plural, from diseases). These forms illustrate how Finnish marks case and number on a common stem to convey different grammatical relations.

Usage notes

Tauteihin is a standard, neutral form found in written Finnish and formal speech, particularly in medical, scientific, or descriptive contexts. In everyday language, speakers may use similar constructions with singular forms or different verbs depending on the exact meaning (for example, contracting a single disease with tautiin). The plural illative is less common in casual speech but is correct when referring to illnesses collectively.
