Tossica

Tossica is the feminine singular form of the Italian adjective tossico, meaning toxic or poisonous. In Italian, tossica is used to describe substances, agents, or conditions that can cause harm or illness, for example una sostanza tossica (a toxic substance) or gas tossico (toxic gas). It can also describe non-physical contexts, such as environmental or relational harm, with expressions like ambiente tossico or relazione tossica.

In addition to its adjectival use, tossica can function as a common, informal noun referring to a woman who uses illegal drugs habitually. This slang usage is pejorative and considered inappropriate in formal writing. The corresponding masculine form is tossico.

Etymology and related terms: Tossica derives from the Latin toxicus, itself from the Greek toxikos (poisonous), ultimately linked to the Greek pharmakon meaning poison. The root tox- appears in many related terms across languages, such as toxin, toxicity, and toxicology. In Italian, the scientific term for the study of poisons is tossicologia, and tossina denotes a toxin.

Usage notes: In formal Italian, prefer tossico for the adjective and avoid slang senses of tossica when writing in professional or academic contexts. The term also appears in phrases describing harmful environments, relationships, or cultural dynamics, e.g., un ambiente tossico, una relazione tossica, una cultura tossica.
