What is war cry? How to use in English

The term "war cry" can be traced back to ancient times, when armies would let out loud, aggressive noises as a means of intimidating their enemies and rallying themselves. The exact roots of this phenomenon are unclear, but it's believed that animal folklore played a role in shaping the concept of a war cry. In many cultures, warriors would imitate the sounds of beasts like lions, wolves, and eagles, in order to invoke their strength and fierce nature. The idea being that by channeling this primal energy, soldiers could tap into a primal sense of power and confidence. This notion of a war cry became firmly etched in history during medieval times, where knights would trumpet battle cries and shouts to inspire their men and signal the charge. Over time, the meaning of a war cry has evolved beyond its original significance. While it still serves as a means of intimidation and motivation on the battlefield, it's also come to symbolize various cultural rituals and traditions. For instance, certain Indigenous tribes in America use war cries as part of their dance and spiritual ceremonies, while some European cultures see war cries as a way to honor their ancestors' military history. Ultimately, the origins of the word "war cry" are diverse and complex, but its enduring appeal demonstrates that it remains a potent and profound aspect of human expression - one that spans time, culture, and geography.
