mittenakkuslikeks

Mittenakkuslikeks is an Estonian grammatical form, specifically the translative plural form of the adjective mittenakkuslik, which means “not infectious.” It is used to express a change of state into non-infectious for a plural subject. In practice, it appears mainly in technical or scientific texts, particularly in epidemiology or microbiology, where processes are described as becoming non-infectious.

The form is built from the negation element mitte, the root nakkus- meaning infection, and the suffix -lik to create the adjective mittenakkuslik (“non-infectious”). The translative plural ending -eks marks a shift into a new state for multiple subjects. For singular usage, the corresponding form would be mittenakkuslikuks; for plural subjects, mittenakkuslikeks is used. The typical construction involves a verb of becoming, such as muutuma (to become): nad muutusid mittenakkuslikeks (they became non-infectious).

Examples of usage include sentences like: Nad muutusid mittenakkuslikeks. (They became non-infectious.) Need katsed näitasid, kuidas haiguspuhang muutus mittenakkuslikeks vastavalt ravile. (Those tests showed how the outbreak changed to a non-infectious state under treatment.) While valid in formal texts, mittenakkuslikeks is rarely needed in everyday speech, where mittenakkuslik and related forms are often sufficient.
