Idioms
This morning in a Poetry discussion I used the idiom 'learn by heart'. Later someone else used 'off by heart'. Well ... draped elegantly on the sofa, glass of wine in hand, doing a lot of nothing - I began to ponder - why 'heart'? Had to go and look it up and - guess what - according to Bloomsbury International - it's all due to those Ancient Greeks again.
To memorise something perfectly, so that it can be written, recited or performed without thinking. To learn something by heart means that you have
understood it before committing it to memory, whereas the similar phrase to learn something by rote often means to memorise without understanding.
Origin
It may seem strange that this phrase credits the ability to remember to the heart instead of to the brain. However, it all goes back to the Ancient Greeks – they believed that the heart was the home of not only emotion, but also of intelligence and memory. This belief was passed on for centuries and led to the creation of the idiom “to learn something by heart” which was commonly used by the 1300s, when the English writer Chaucer recorded the phrase in his play Troilus and Cressida.
Do we all feel better for knowing that? Good - I'll go back to the wine!
