If you are fortunate enough to be invited to a Passover celebration, you may want to brush up on some of the basic terminology. Here is a short glossary to help you feel more knowledgeable.

Pesach (PEH-sach)—the Hebrew word for Passover. The word is used for the holiday itself and also for the Paschal sacrifice.

Matzoh (MAH-tzoh)—literally without leaven," or unleavened bread. Matzoh has a cracker-like texture and is generally the size of a dinner plate.

Afikomen (Ahfee-KO-men)—literally "that which comes last." The hidden matzoh that is taken out and eaten at the end of the seder meal.

Haggadah (Ha-GAH-dah)—literally "the telling." The Haggadah is the common service book used at the Passover celebration. It contains the Exodus account from Scripture, rabbinic comments and traditions, holiday songs and prayers.
