IPA: //dɪˈkuːmərɒl//
KK: /dɪˈkuːmərɒl/
A type of medicine that prevents blood from clotting, used to treat certain medical conditions.
The doctor prescribed dicoumarol to help manage the patient's blood clotting issues.
Dicoumarol is formed from "di-" (meaning two) and "coumarin" (a compound derived from the tonka bean, which has a sweet scent). The word refers to a substance that is a derivative of coumarin, specifically with two coumarin units, used as an anticoagulant.
Think of 'two' ('di-') coumarin units combined to create a substance that helps prevent blood clotting.
