• Many students try to learn model answers by heart before the IELTS Speaking test.

The interesting point of the idiom Learn by heart lies in the word heart. Why is memorization associated with the heart, instead of the brain?

This expression is rooted in the ancient Greek notion that the heart is not only the organ that creates life, but also the center of all emotions, thoughts, souls, and especially memory. In Old English, the word heart not only means heart in an anatomical sense, but is also used to refer to spirit, will, courage, mind, and intellect.

Over time, this concept gradually entered European language and culture, especially through the French phrase apprendre par cœur, meaning "learning by heart". This expression is said to have influenced English, creating the phrase learn by heart to refer to memorizing something carefully.

Today, although modern science has proven that it is the brain that processes and stores memories, the phrase learn by heart is still commonly used in everyday English. When saying learn something by heart, native speakers do not take it literally, but understand that it is memorized so well that it can be repeated without looking at the document.
