A manger is a wooden, metal, or stone trough from which animals eat (especially horses and cattle). 

The word is linked to the French word mangeoire, which itself comes from the French word manger, which means to eat

The word manger will remind many people of  Jesus' birth at Bethlehem, as described in the Christian Bible:

And she brought forth her firstborn son, and wrapped him in swaddling clothes, and laid him in a manger; because there was no room for them in the inn. (Luke 2:7 - King James version).
