Desperta Ferro!

Desperta ferro is a phrase that comes from the language of Spanish during the Middle Ages. It means "wake up, iron!" and it was used as a battle cry by soldiers when they were about to fight.

Imagine that you are playing a game with your friends, and you are pretending to be soldiers. You have swords and shields and you are ready to fight the other team. When you shout "Desperta ferro!", it's like you are saying "wake up, iron!" to your sword. You want your sword to be strong and powerful, just like you.

Sometimes, soldiers would even hit their swords against their shields to make a loud noise when they shouted "Desperta ferro!" They did this to intimidate the enemy and show them that they were ready for battle.

So, as a 5-year-old, "Desperta ferro!" is a cool phrase that means "wake up, sword!" and it's what soldiers used to yell before fighting.
