Kuolettavat

Kuolettavat is a Finnish adjective meaning “lethal” or “deadly.” It is the plural nominative form of the adjective kuolettava, used to describe plural nouns that can cause death or produce fatal effects. The base kuolettava comes from the verb kuolettaa, meaning to kill or to cause death, with the -va suffix that forms adjectives. The related noun form describing lethality is kuolettavuus.

In usage, kuolettavat appears in technical and regulatory language to classify hazards. Common phrases include kuolettavat aineet (deadly substances), kuolettavat kaasut (lethal gases), and kuolettavat annokset (lethal doses).
