覚え方のコツ Memory Tip
anti- は antibiotic, anti-inflammatory などでおなじみの「〜に対抗する」。まずここで「何かを抑える語」だとつかむ。platelet は plate「平たい板」+ -let「小さいもの」で、小さな板のような blood cell を指す語。つまり antiplatelet は「血小板の働きを抑える」。 clot を直接止める anticoagulant と近いが、こちらは特に platelet aggregation を防ぐ場面で使うと整理すると覚えやすい。antiplatelet drug, antiplatelet therapy の形でも頻出。
`Anti-` means against, so the first part already tells you this word blocks something. `Platelet` is the blood word to remember here, so `antiplatelet` means working against platelet action. Keep it in the medical phrase `antiplatelet therapy`, and connect it with stopping platelets from sticking together. That helps you separate it from `anticoagulant`, which is close but not the same focus.

antiplatelet の語源・成り立ち Etymology
anti-はギリシャ語由来で「反対」、plateletはフランス語系の plate に指小辞 -let が付いた「小さな平板」。皿のような形の血小板に働きを逆らう語なので「抗血小板」となり、antibody や plateau が形と意味の手掛かりになる。
Antiplatelet is formed from anti- "against" and platelet. Anti- comes from Greek, and platelet comes from plate with the small-form ending -let, from French. The word was built to mean something that acts against platelets, whose name comes from their flat, plate-like shape. Related words include antibody and plateau.
