IPA: /ˌæntɪˈvɛnɪn/
KK: /ˈæntɪˌvɛnɪn/
A medicine made from animal serum that helps treat poisoning caused by the venom of snakes, spiders, or other poisonous creatures.
The doctor administered antivenin to the patient who was bitten by a snake.
Antivenin is formed from "anti-" (meaning against) and "venenum" (from Latin, meaning poison). The word describes a substance that works against or counteracts poison, particularly from snake bites or venomous creatures.
Think of 'against' ('anti-') and 'poison' ('venenum') to remember that antivenin is something that counteracts poison.
