What does venin mean?
Venin is a specialist term for a poisonous substance found in venom, especially a toxic protein or other constituent of an animal's venomous secretion. It is more specific than “venom”: venom denotes the whole secretion used to deliver toxins, whereas a venin is the poisonous material or component within it. The term is encountered chiefly in biochemistry, toxicology, and venom research, including descriptions of a particular venin's action, potency, or molecular structure. In ordinary conversation, “venin” is uncommon, and using it for any poison or all of snake venom would be misleading. Venin's interest lies in its precision: it helps researchers distinguish the carrier of a toxin from the toxin-bearing substance itself. Although closely related etymologically to words such as venom and venomous, it has a narrower modern technical meaning.
nounA poisonous substance, especially a toxic constituent of venom produced by an animal. The term may also refer more generally to venom or poison.
- A poisonous substance or toxic constituent found in venom.
"The researchers isolated a potent venin from the snake's venom and tested its effects in laboratory animals."
"The peptide was identified as a venin responsible for the venom's neurotoxic effects."
"In her research on antivenom, she studied how the body responds to different venins."
The plural is uncommon and is generally used when referring to distinct poisonous constituents.
"The study compared the activity of several venins isolated from different species."
Venom is the delivery system; venin is part of the poisonous cargo.

Etymology of venin
The English word came through French venin, meaning “poison” or “venom,” from Latin venenum, “poison.” In English, it came to denote a poisonous constituent of venom. The Latin root also underlies words such as venom, venomous, and venenate, all belonging to the family of poison-related vocabulary.
How venin is actually used
Chiefly a technical term used in biochemistry, toxicology, and venom research. It is uncommon in general English, and using it for every poison or for an entire secretion of venom is imprecise.
Easily confused with venin
Venom is the entire secretion used by an animal to deliver toxins, whereas venin refers more specifically to a poisonous constituent of that secretion.
