cờ đen
/ˌblæk ˈflæɡ//ˌblæk ˈflæɡ/The original Jolly Roger was a plain black flag with no decoration, devoid of any identifying markings. It signified that the ship flying it was a pirate vessel and that no mercy would be shown to any onboard. Pirates typically hoisted this flag when they wanted to intimidate their victims or when they wished to seek vengeance against their enemies. However, the origin of the term "black flag" itself is somewhat unclear as the pirates did not typically refer to their flag as such. In reality, other ships' crews would use the term "black flag" to describe any ship that they saw flying the plain black flag, as it was a symbol of fear and danger on the seas. In today's context, "black flag" is still used to connote something ominous or foreboding but has extended beyond the nautical world to include any entity that may bring harm, such as natural disasters like tornadoes or social issues like police brutality. In this sense, the term has evolved to encompass a broader range of meanings while retaining its historical significance as a symbol of danger and intimidation.
