The word for today is CORDIAL. This may be taken in two ways. It is a warm cozy meaning and we shall take a look at the origin. The Latin word – COR, CORDIS (gen. sing.) means HEART. If something is CORDIAL, it is from THE HEART.
The ancient Romans believed that the heart was the seat of not only our emotions but also of memory. That is why the word RECORD means TO BRING BACK TO THE HEART. The Latin prefix RE means BACK, BACK AGAIN. Today we know that the seat of memory is not in the heart but in the head.
The instrument ACCORDION and the word ACCORD means TO BE NEAR THE HEART. The AC in front of COR comes from the Latin preposition AD which means NEAR, TO, TOWARD.
DISCORD means APART FROM THE HEART, THE HEARTS ARE APART. The Latin prefix DIS means APART.
CONCORD and CONCORDIA mean TO BE TOGETHER, the hearts are together, in agreement. The Latin preposition CUM, CON means WITH, TOGETHER.
A CORDATE shaped seashell is of course HEART-SHAPED.
