süstunud

Süstunud is an Estonian word that functions as a past participle of the verb süstima (to inject). It is used as an adjective meaning “injected” or “administered by injection,” and it can describe substances, medicines, or people who have received an injection.

Etymology and related forms: The form süstunud is built from the stem süst- plus the participial suffix -unud, creating a participial adjective. It is closely related to other forms such as süstitud (also meaning injected) and the noun süstitus (the act of injection or administration). The exact usage can vary with style and regional preference.

Usage: In medical and everyday language, süstunud denotes that an injection has been performed or that a substance has been administered by injection. While both süstunud and süstitud convey a similar sense, speakers may choose one form over the other depending on stylistic factors. In formal medical writing, alternative constructions or explicit verbs may be used to maintain precision.
