Late Middle English (as a noun denoting heart disease): from French cardiaque or Latin cardiacus, from Greek kardiakos, from kardia 'heart or upper opening of the stomach'. The adjective dates from the early 17th century.

  • heart from Old English:

    The Greek word kardia, from which English took cardiac (Late Middle English), is directly related to heart. The shared root existed before their ancestor developed into different language families in Europe, Asia, and northern India. Since Anglo-Saxon times people have regarded the heart as the centre of emotions and feelings. If you wear your heart on your sleeve, you make your feelings clear for all to see. In a television interview in 1987 the former British Prime Minister Margaret Thatcher advised against it, saying: ‘To wear your heart on your sleeve isn't a very good plan; you should wear it inside, where it functions best.’ The phrase has its origins in chivalry. In the Middle Ages, when jousting was a popular form of entertainment, a knight would tie a favour to his sleeve—a ribbon, glove, or other small item belonging to the lady given as a sign of her love or support.
