IPA: /ˌæn.tiˈpleɪt.lɪt/
KK: /ˌæntiˈpleɪtlɪt/
Describing something that works to prevent or reduce the activity of blood platelets, which are cells involved in blood clotting.
The doctor prescribed an antiplatelet medication to help prevent blood clots.
Antiplatelet is formed from "anti-" (meaning against) and "platelet" (from the Greek "platus", meaning flat, referring to the small, disc-shaped cell fragments in the blood). The word antiplatelet refers to substances that work against the action of platelets in the blood, often used in the context of preventing blood clots.
Think of 'anti-' meaning against, and 'platelet' referring to the small blood cells that help with clotting. This helps you remember that antiplatelet means something that works against blood clotting.
