A chuppah is like a big tent that two people stand under when they get married in a Jewish ceremony. The chuppah is made of four poles (kind of like really tall sticks) and a piece of material, like a sheet or a blanket, that covers the top of the poles. The couple and sometimes their close family members stand underneath the chuppah during the ceremony. It's like a special place where the couple can be together and make promises to each other about their marriage.
