myrkyllisenä

Myrkyllisenä is a Finnish word-form derived from the adjective myrkyllinen, meaning poisonous or toxic. It is the essive (state or role) form used to describe being in a poisonous state or to express that something is used or regarded as poison in a given context. The term appears in both everyday language and specialized texts to convey a temporary state or a functional role rather than an inherent, permanent property.

In grammar, myrkyllisenä is the essive singular form of myrkyllinen. The related forms include myrkyllisempi (comparative) and myrkyllisin (superlative). Typical constructions use essive forms with nouns to indicate the state or role, for example: kasvi voidaan pitää myrkyllisenä (a plant can be regarded as poisonous) or se toimi myrkyllisenä aineena (it acted as a poisonous substance). The root etymology comes from myrkky (poison) plus the adjectival suffix -llinen, with essive -na/-nä marking the state or role.

Usage context and nuance: myrkyllisenä is common in toxicology, pharmacology, ecology, safety warnings, and legal or risk-communication texts to describe properties, classifications, or official assessments in a context-dependent way. It emphasizes status or function rather than an absolute characteristic, and is often paired with nouns such as aineena (as a substance) or pidetty (considered).
