Usage Note
Caillot almost always refers to a blood clot (un caillot de sang) in medical French, though it can describe any small coagulated or congealed lump. The verb cailler means 'to clot' or 'to curdle'. In informal speech, cailler also means 'to be freezing cold', so context matters.
Examples
"Un caillot bloquait l'artère."
Natural Translation
