zehre

Zehre is a term encountered in Urdu and Hindi, as well as Persian-influenced lexicons, that denotes poison or a poisonous substance. The primary modern spellings in these languages are zehar or zehr (Urdu: زہر; Hindi: ज़हर). The form "zehre" appears in some transliterations or dialectal usage and may be found in literary or niche contexts as a variant.

Etymology and cognates: The word derives from a common Semitic-Persian root for venom and poison, with cognates in Persian zehr and Turkish zehir. These terms all broadly denote substances that can cause harm, illness, or death.

Usage and cultural context: In daily language, zehar/zehr denotes any poisonous substance. In literature, poetry, and media, the word is often used metaphorically to describe toxic influence, deceit, or danger. In toxicology and public health, poisons are studied to understand their effects, exposure limits, and treatment after exposure.

Safety and regulation: Poison management involves regulation, safety data, and medical response. Accurate identification and avoidance of poisonous substances are essential to prevent accidental poisoning. The term zehar remains a general descriptor rather than a specific chemical class.
