anticoagulants
抗凝固剤
解説 Definition
抗凝固剤。血液の凝固を防ぐ薬物。血栓を防ぐために医学的に処方される物質。
Anticoagulants are medicines or substances that help prevent blood from clotting too easily. They are used in medical treatment to reduce the risk of dangerous blood clots. The word is common in healthcare and medical contexts.
覚え方のコツ Memory Tip
まず anti- は「反対・防ぐ」の定番接頭辞で、antibiotic などと同じ型。中心は coagulate「固まる・凝固する」で、coagulation は血液が固まること。つまり anti + coagulant で「固まる方向を止めるもの」と分かる。医療では anticoagulants = blood thinners とも呼ばれ、血栓予防の文脈で出やすい。clot を『できた血のかたまり』、coagulate を『固まっていく動き』として対比すると定着しやすい。
Use the parts: `anti-` means against, and `coagulate` means become thick or solid. So the word points to stopping that solidifying process. It is also often linked with `blood thinners`, which gives you a strong medical collocation to remember.

anticoagulants の語源・成り立ち Etymology
ギリシャ語 anti-(反対)+ラテン語 coagulare(凝固させる)+-ant(作用するもの)の組み合わせ。coagulare は co-(共に)+agere(動かす)が語源で、「寄せ集めて固める」が原義。関連語:coagulate(凝固する)、antibiotic(抗生物質)。
"Anticoagulants" is built from Greek "anti-" meaning "against," Latin "coagulare" meaning "to cause to clot," and the ending "-ant" for something that acts. "Coagulare" is related to gathering or driving things together into a mass. So the word originally meant substances that act against clotting; compare "coagulate" and other "anti-" words such as "antibiotic."
