## Meaning

To become enraged, angry, or irritated.

## Examples

- The politician tried to remain calm during the debate, but he began to see red when his opponent questioned his integrity in front of the entire audience.

## Origin

The origins of the expression are unsettled, though several theories involve the more strenuous uses of the colour. It is said to derive from the red flag historically raised by certain armies to signal that battle was imminent, or perhaps from the red cloth used to provoke bulls in Spanish bullfighting. A more general explanation links the phrase to the status of red as a universal signifier of warning and danger. The idiom is well represented across the continent, with corresponding forms in several European languages. These include the Danish *se rødt*, the German *rotsehen*, and the French *voir rouge*. Whether the metaphor rests on military signals or the arena, the linguistic result remains a shared standard for the onset of fury. (disputed)
