You have probably met someone whose face gives everything away, someone who cannot hide excitement, heartbreak, or love even if they tried. In English, we call such a person someone who wears their heart on their sleeve.

- My grandmother wore her heart on her sleeve her whole life, and people loved her for it.
- In negotiations, it rarely pays to wear your heart on your sleeve
The expression is often linked to medieval jousting tournaments. When a knight rode into the arena, he might tie a scarf or ribbon (a “favor”) belonging to the lady he admired around his sleeve as a public declaration of his affection and loyalty. This traditional explanation captures the idea of a bold, visible gesture, though it is not the only possible origin and not proven as the sole source of the phrase.
By the early 17th century, Shakespeare had already woven the phrase into Othello, where the scheming Iago uses it with biting irony, pretending to be emotionally open while concealing his true treacherous intent.
Today, wearing your heart on your sleeve carries a double edge: it speaks about honesty and emotional courage—the willingness to be seen as you truly are. But it also signals vulnerability. When feelings are this visible, they invite both warmth and the occasional wound.
Perhaps that is precisely what makes it so human.
