Definition of the word clot

The word "clot" has its roots in Old English, dating back to the 9th century. It is derived from the Proto-Germanic word "klotiz", which means "lump" or "mass". This Proto-Germanic word is also the source of the Modern English word "clod", meaning a lump of earth. In Old English, the word "clot" referred to a mass or lump of something, such as a clot of blood or a clot of wool. Over time, the meaning of the word expanded to include other types of clumps or masses, such as a clot of ice or a clot of people. In medical contexts, a clot refers to a lump or mass of blood that has formed in a vessel, such as a blood clot that has formed in a vein or artery.
