Questions & Answers about El cor funciona bé.
In Catalan, nouns are very often used with an article, even in cases where English might leave it out.
So el cor means the heart, and in a sentence like this it sounds natural and complete. Saying just cor would usually sound incomplete unless it appeared in a special context, such as a heading, label, or poetic style.
Catalan often uses the definite article with body parts when the owner is already clear from context.
So instead of saying my heart works well, Catalan will often say something closer to the heart works well, with the understanding that the relevant person's heart is meant.
This is very common with body parts:
- Em fa mal el cap = My head hurts / literally The head hurts me
- Té els ulls blaus = He/She has blue eyes / literally has the blue eyes blue
