Why Do Idioms for Heart Exist in English?
English has many idioms for heart because people long ago believed the heart, not the brain, was the home of thought and feeling.
The Greek thinker Aristotle called the heart the organ of sensation. The Old English word was heorte, and it already carried ideas like courage, memory, and emotion. Most of the figurative senses we use today were already in place then. Also learn other idioms that are about Teamwork and Peace.
Science later showed that the brain thinks. The old phrases stayed anyway. That is why you “learn by heart” and not “by brain,” and why a brave person “has heart.” Many idioms for heart trace back to that old belief.

Warm the Cockles of Your Heart
Its first written use dates to 1671. Nobody has settled where “cockles” comes from. One theory links it to the cockle shell, which looks a bit like a heart. Another points to Latin words for the heart’s chambers. A third points to a Latin word for “little heart.”

Common Mistakes with Idioms for Heart
Learners most often slip on word order, tone, and fixed wording when they use idioms for heart.
- Mixing up “take heart” and “take to heart.” Wrong: “She took heart his advice.” Right: “She took his advice to heart,” or “She took heart from his advice.”
- Using “my heart bleeds for you” to comfort someone. It usually sounds sarcastic. Say “my heart goes out to you” instead.
- Using “eat your heart out” as sympathy. Today it is a playful boast, as in “I won two tickets. Eat your heart out!”
- Changing the fixed wording. Say “a heart of gold,” not “a golden heart.” The phrase works best in its set form.
- Setting your heart on a person. Use “set your heart on” for goals and things, like a job or a trip. For a person, try “lose your heart to” instead.
- Overdoing “from the bottom of my heart.” It sounds too big for tiny favors. Save it for real thanks and real apologies.
