Bonsoir pouvez-vous m'aider svp je dois faire un résumer en anglais des intentions et des caractéristiques des white walkers et des wights

White Walkers, also known as Others in the books, are not dead but instead are a sort of magical humanoid life form. On the show, we know they were created from men thanks to a flashback Bran had showing the Children of the Forest making the Night King by plunging a dragonglass dagger into his heart.

The White Walkers definitely have a language.  

White Walkers also carry swords crafted using their brand of magic — swords that can shatter regular steel and easily slice through men's flesh.

In the show, the White Walkers are led by a character named the Night King. He is also a White Walker, just a special type given that he was the first one ever made.

White Walkers can be killed with either dragonglass or Valyrian steel, and maybe even dragonfire. But regular fire or steel does not harm them.

"Wight" is a catch-all term for the reanimated corpses of humans.They can be reanimated when their corpse has rotted down to the bone, as we also saw in "Hardhome." As we now know from "Beyond the Wall," if someone kills a White Walker, then the wights that particular White Walker rose from the dead will also fall. Wights can be killed with regular fire, and in "Beyond the Wall" it looked like Jon Snow and his fellow fighters were killing them using dragonglass as well.
