Ma Nishtana
Ma Nishtana (), are the first two words in a phrase meaning "Why is tonight different from all other nights?" The phrase appears at the beginning of each line of The Four Questions, traditionally asked via song by the youngest capable child attending Passover Seder. The questions are included in the haggadah as part of the Maggid (מגיד) section. Origins. The questions originate in the Mishna, Pesachim 10:4, but are quoted differently in the Jerusalem and Babylonian Talmuds. The Jerusalem Talmud only records three questions; why foods are dipped twice as opposed to once, why matzah is eaten, and  why the meat sacrifice eaten is exclusively roasted. (The last question is a reference to the paschal sacrifice which was fire-roasted). The Babylonian Talmud quotes four questions; why matzah is eaten, why maror is eaten, why meat that is eaten is exclusively roasted, and why food is dipped twice. The version in the Jerusalem Talmud is also the one most commonly found in manuscripts. As the paschal sacrifice was not eaten after the destruction of the temple, the question about the meat was dropped. The Rambam and Saadia Gaon both add a new question to the liturgy to replace  it: "why do we recline on this night?" Ultimately, the question of reclining was maintained, in part to create a parallelism between the number of questions and the other occurrences of the number four in the hagaddah. Contemporary tunes. Traditionally, "Ma Nishtana" is recited in the chant form called the major "lern-steiger" ("study mode" – a chant used for reciting lessons from the Talmud or Mishnah). One of the current tunes widely used for the Ma Nishtana was written by Ephraim Abileah in 1936 as part of his oratorio "Chag Ha-Cherut". Text. The following text is that which is  recorded in the original printed Haggadah. Alternate order. In the Ashkenazi tradition, the order is as follows: 1. Eating matzah 2. Eating bitter herbs 3. Dipping the food 4. Reclining. The Ashkenazi communities also omit the use of the word "ushotin", which means "to drink". The Chabad communities have changed their Ashkenazi tradition to be in line with the oldest extant haggadot. History. A fifth question which is present in the mishnah has been removed by later authorities due to its inapplicability after the destruction of the Second Temple: The four questions have been translated into over 300 languages. Answers . The answers to the four questions (and the historic fifth question) are: Some of these answers are stated over the course of the Seder. Contemporary use. The four questions are traditionally asked by the youngest person at the table that is able to do so. Much of the seder is designed to fulfill the biblical obligation to tell the story to one's children, and many of the customs that have developed around the Four Questions are designed to pique a child's curiosity about what is happening in order to hold their attention.
